IC Packaging is suited for analog products.
NanoStar(TM) wafer chip-scale packaging (WCSP) has no molding compound, lead frame, wire bonds, or leads. Using surface-mount technology assembly procedures, packaging can be mounted to PCB without additional under fill. Available power management ICs include RF LDO regulator; DC/DC buck converter; dual operational amplifier; audio power amplifier; and digital-to-analog converter with serial...

Step-Down Converters provide up to 95% power efficiency.
Series TPS6222x consists of 400 mA, synchronous DC/DC converters that support input voltage from 2.5-6 V, output voltage of 6 V down to 0.7 V, and output current up to 400 mA. They operate with fixed switching frequency of 1.25 MHz. In Power Save Mode, switching frequency is reduced and quiescent current is typically 15 Ã-µA. Converters come in 5-pin ThinSOT-23 package and are suited for...

CMOS Op Amps drive 16-bit data converters.
Models OPA725 and OPA726 are 12 V, high-speed operational amplifiers that achieve 20 MHz bandwidth, 30 V/Ã-µs slew rate, and 0.0003% harmonic distortion with 16-bit settling time. Input common-mode range extends to ground for true single-supply operation, and output swings to within 150 mV of rails, maximizing dynamic range. Both are specified for operation from -40 to +125Ã-

PWM Driver controls electromechanical and thermal devices.
DMOS 1.5 A driver Model DRV104 operates from single 8-32 V supply range. It can provide strong initial solenoid closure and automatically switch to soft hold mode for power savings. Duty cycle can be controlled by resistor, analog voltage, or digital-to-analog converter. Status flag pin indicates thermal shutdown or over-current conditions. Separate supply pins for control circuitry and driver...

Digital-to-Analog Converter suits communication systems.
Model DAC2932 dual, 12-bit, 40 MSPS converter features 29 mW power dissipation, 75 dB spurious-free dynamic range, 2.7-3.3 V single-supply operation, and integraton of four 12-bit voltage-output DACs for signal path control. Further optimization can be achieved by lowering output current with adjustable full-scale range of 0.5-2 mA. Power-down mode reduces power dissipation to only 25 Ã-µW....
