Product Summary

The OPA2344UA rail-to-rail CMOS operational amplifier is designed for precision, lowpower,
miniature applications. The OPA2344UA is unity gain stable, while the OPA345 is optimized for gains greater than or equal to five, and has a gain-bandwidth product of 3MHz. The device is optimized to operate on a single supply from 2.5V and up to 5.5V with an input common-mode voltage range that extends 300mV beyond the supplies. Quiescent current of the OPA2344UA is only 250mA (max).

Parametrics

OPA2344UA absolute maximum ratings: (1)Supply Voltage, V+ to V-: 7.5V; (2)Signal Input Terminals, Voltage: (V–) –0.5V to (V+) +0.5V; Current: 10mA; (3)Output Short-Circuit: Continuous; (4)Operating Temperature: –55℃ to +125℃; (5)Storage Temperature: –65℃ to +150℃; (6)Junction Temperature: 150℃; (7)Lead Temperature (soldering, 10s): 300℃; (8)ESD Tolerance (Human Body Model): 4000V.

Features

OPA2344UA features: (1)rail-to-rail input; (2)rail-to-rail output (within 1mV); (3)low quiescent current: 150mA typ; (4)microsize packages: SOT23-5, MSOP-8, TSSOP-14; (5)gain-bandwidth: OPA344: 1MHz, G≥1, OPA345: 3MHz, G ≥ 5; (6)slew rate: OPA344: 0.8V/ms; OPA345: 2V/ms; (7)thd + noise: 0.006%.
