Single SoundPlus™ 8-MHz, 50-pA, High Performance Audio Operational Amplifiers with FET inputDescription: The OPA134 series are ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. A true FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. This, in combination with high output drive capability and excellent DC performance, allows for use in a wide variety of demanding applications. In addition, the OPA134 has a wide output swing, to within 1 V of the rails, allowing increased headroom and making it ideal for use in any audio circuit. The OPA134 SoundPlus™ audio operational amplifiers are easy to use and free from phase-inversion and the overload problems often found in common FET-input operational amplifiers. They can be operated from ±2.5-V to ±18-V power supplies. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range, minimizing distortion. OPA134 series operational amplifiers are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions, including high load capacitance. The dual and quad versions feature completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded. Single and dual versions are available in 8-pin DIP and SO-8 surface-mount packages in standard configurations. The quad is available in 14-pin DIP and SO-14 surface mount packages. All are specified for –40°C to 85°C operation. A SPICE macromodel is available for design analysis.Features:• Superior Sound Quality• Ultra Low Distortion: 0.00008%• Low Noise: 8 nV/vHz• True FET-Input: IB = 5pA• High Speed:- Slew Rate: 20 V/µs- Bandwidth: 8 MHz• High Open-Loop Gain: 120 dB (600 O)• Wide Supply Range: ±2.5 V to ±18 V• Single, Dual, and Quad Versions

The bq2409x series of devices are highly integrated Li-ion linear chargers devices targeted at space-limited portable applications. The devices operate from either a USB port or AC adapter. The high input voltage range with input overvoltage protection supports low-cost unregulated adapters.

The LM2621 is a high efficiency, step-up DC-DC switching regulator for battery-powered and low input voltage systems. It accepts an input voltage between 1.2V and 14V and converts it into a regulated output voltage. The output voltage can be adjusted between 1.24V and 14V. It has an internal 0.17 ? N-Channel MOSFET power switch. Efficiencies up to 90% are achievable using the LM2621.

DescriptionThe ’HC597 and CD74HCT597 are high-speed silicon gate CMOS devices that are pin-compatible with the LSTTL 597 devices. Each device consists of an 8-flip-flop input register and an 8-bit parallel-in/serial-in, serial-out shift register. Each register is controlled by its own clock. A “low” on the parallel load input (PL) shifts parallel stored data asynchronously into the shift register. A “low” master input (MR) clears the shift register. Serial input data can also be synchronously shifted through the shift register when PL is high.

50-V, 7-ch darlington transistor array DescriptionThe ULx200xA devices are high-voltage,high-current Darlington transistor arrays. Each consists of seven NPN Darlington pairs that featurehigh-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is 500 mA. The Darlington pairscan be paralleled for higher current capability. Applications include relay drivers, hammerdrivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers. The ULx2004A devices have a 10.5-k? series base resistor to allow operation directly from CMOS devices that use supply voltages of 6 V to 15 V. The required input current of the ULx2004A device is below that of the ULx2003A devices, and the required voltage is less than that requiredby the ULN2002A device.Features:• 500-mA-Rated Collector Current (Single Output)• High-Voltage Outputs: 50 V• Output Clamp Diodes• Inputs Compatible With Various Types of Logic• Relay-Driver Applications

0.1% 3-ppm/°C precision micropower low-dropout series voltage reference with enable pin

The TPS54160A device is a 60-V, 1.5-A, step down regulator with an integrated high-side MOSFET. Current mode control provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no load, regulated output supply current to 116 µA. Using the enable pin, shutdown supply current is reduced to 1.3 µA.

LM2940x 1-A Low Dropout RegulatorDescriptions:The LM2940-N and LM2940C positive voltage regulators feature the ability to source 1 A of output current with a dropout voltage of typically 0.5 V and a maximum of 1 V over the entire temperature range. Furthermore, a quiescent current reduction circuit has been included which reduces the ground current when the differential between the input voltage and the output voltage exceeds approximately 3 V. The quiescent current with 1 A of output current and an input-output differential of 5 V is therefore only 30 mA. Higher quiescent currents only exist when the regulator is in the dropout mode (VIN - VOUT = 3 V). Designed also for vehicular applications, the LM2940-N and LM2940C and all regulated circuitry are protected from reverse battery installations or 2-battery jumps. During line transients, such as load dump when the input voltage can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both the internal circuits and the load. The LM2940-N and LM2940C cannot be harmed by temporary mirror-image insertion. Familiar regulator features such as short circuit and thermal overload protection are also provided.Features:• Input Voltage Range = 6 V to 26 V• Dropout Voltage Typically 0.5 V at IOUT = 1 A• Output Current in Excess of 1 A• Output Voltage Trimmed Before Assembly• Reverse Battery Protection• Internal Short Circuit Current Limit• Mirror Image Insertion Protection• P+ Product Enhancement Tested
