DESCRIPTION The OPA322 series consists of single, dual, and quad-channel CMOS operational amplifiers featuring low noise and rail-to-rail inputs/outputs optimized for low-power, single-supply applications. Specified over a wide supply range of 1.8 V to 5.5 V, the low quiescent current of only 1.5 mA per channel makes these devices well-suited for power-sensitive applications. FEATURES • Gain Bandwidth: 20 MHz • Low Noise: 8.5 nV/√Hz at 1 kHz • Slew Rate: 10 V/μs • Low THD+N: 0.0005% • Rail-to-Rail I/O • Offset Voltage: 2 mV (max) • Supply Voltage: 1.8 V to 5.5 V • Supply Current: 1.5 mA/ch – Shutdown: 0.1 μA/ch • Unity-Gain Stable • Small Packages: – SOT23, DFN, MSOP, TSSOP
The OPA2322AIDGKT is a dual low noise CMOS Operational Amplifier with rail-to-rail input and output. Specified over a wide supply range of 1.8 to 5.5V, the low quiescent current of only 1.5mA per channel makes these devices well-suited for power-sensitive applications. The combination of very low noise (8.5nV/√Hz at 1kHz), high gain-bandwidth (20MHz) and fast slew rate (10V/µs) make the OPA322 family ideal for a wide range of applications, including signal conditioning and sensor amplification requiring high gains. Featuring low THD+N, the OPA322 series is also excellent for consumer audio applications, particularly for single-supply systems.
Product Details The AD8613 / AD8617 / AD8619 are single, dual, and quad micropower, rail-to-rail input and output amplifiers that feature low supply current, as well as low input voltage and current noise. The parts are fully specified to operate from 1.8 V to 5 V single supply, or ±0.9 V and ±2.5 V dual supply. The combination of low noise, very low input bias currents, and low power consumption make the AD8613 / AD8617 / AD8619 especially useful in portable and loop-powered instrumentation. The ability to swing rail-to-rail at both the input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in low power, single-supply systems. The AD8613 is available in a 5-lead SC70 package and a 5-lead TSOT-23 package. The AD8617 is available in 8-lead MSOP, 8-lead SOIC, and 8-lead LFCSP packages. The AD8619 is available in 14-lead TSSOP and 14-lead SOIC packages. The AD8617W is qualified for automotive applications and is available in 8-lead MSOP and 8-lead SOIC packages. The AD8619W is qualified for automotive applications and is available in 14-lead SOIC and 14-lead TSSOP packages. Applications
