The – LOW OFFSET VOLTAGE: 20 μV combination of low input voltage noise, high gain bandwidth (900kHz), and low power (150 μA max) – LOW OFFSET DRIFT: 0.1 μV/°C enable these devices to achieve optimum • QUIESCENT CURRENT: 125 μA performance for low-power precision applications. In • GAIN BANDWIDTH: 900kHz addition, the excellent PSRR performance, coupled with a wide input supply range of 2.2V to 5.5V and • RAIL-TO-RAIL INPUT/OUTPUT rail-to-rail input and output, makes it an outstanding • EMI FILTERING choice for single-supply applications that run directly • SUPPLY VOLTAGE: 2.2V to 5.5V from batteries without regulation. • microSIZE PACKAGES: SC70 and SOT23 The OPA378 (single version) is available in both a microSIZE SC70-5 and a SOT23-5 package. The APPLICATIONS OPA2378 (dual version) is offered in a SOT23-8 package. All versions are specified for operation from • PORTABLE MEDICAL DEVICES –40°C to +125°C. – GLUCOSE METERS – OXYGEN METERING – HEART RATE MONITORS • WEIGH SCALES • BATTERY-POWERED INSTRUMENTS • THERMOPILE MODULES • HANDHELD TEST EQUIPMENT • SENSOR SIGNAL CONDITIONING 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 microPOWER is a trademark of Texas Instruments Incorporated. 3 All other trademarks are the property of their respective owners.
