SBOS347D – NOVEMBER 2005 – REVISED MAY 2008 1.8V, 2.9 µA, 90kHz, Rail-to-Rail I/O OPERATIONAL AMPLIFIERS 2 • LOW NOISE: 2.8µV PP (0.1Hz - 10Hz) The OPA379 family of micropower, low-voltage • microPower: 5.5µA (max) operational amplifiers is designed for battery-powered • LOW OFFSET VOLTAGE: 1.5mV (max) applications. These amplifiers operate on a supply • DC PRECISION: voltage as low as 1.8V (±0.9V). High-performance, single-supply operation with rail-to-rail capability – CMRR: 100dB (10 µV max) makes the OPA379 family useful for a – PSRR: 2 µV/V wide range of applications. – AOL: 120dB In addition to microSize packages, the OPA379 family • WIDE SUPPLY VOLTAGE RANGE: 1.8V to 5.5V of op amps features impressive bandwidth (90kHz), • microSize PACKAGES: low bias current (5pA), and low noise (80nV/ √Hz) relative to the very low quiescent current (5.5 µA – SC70-5, SOT23-5, SOT23-8, SO-8, TSSOP-14 max). The OPA379 (single) is available in SC70-5, SOT23-5, and SO-8 packages. The OPA2379 (dual) • BATTERY-POWERED INSTRUMENTS comes in SOT23-8 and SO-8 packages. The • PORTABLE DEVICES OPA4379 (quad) is offered in a TSSOP-14 package. • MEDICAL INSTRUMENTS All versions are specified from –40 °C to +125°C. • HANDHELD TEST EQUIPMENT xxx xxx xxx xxx xxx xxx xxx Table 1.
