A single external resistor sets any gain from 1 to 1000. It offers excellent stability over temperature, – 100 dB, min at 5 kHz (G = 10) even at G > 1, as a result of the low gain drift of only • Power-Supply Rejection: 100 dB, min (G = 1) 35 ppm/°C (max). • Low Offset Voltage: 150 µV, max The INA826 is optimized to provide excellent • Gain Drift: 1 ppm/°C (G = 1), 35 ppm/°C (G > 1) common-mode rejection ratio of over 100 dB (G = 10) • Noise: 18 nV/ √Hz, G ≥ 100 over frequencies up to 5 kHz. In G = 1, the common- mode rejection ratio exceeds 84 dB across the full • Bandwidth: 1 MHz (G = 1), 60 kHz (G = 100) input common-mode range from the negative supply • Inputs Protected up to ±40 V all the way up to 1 V of the positive supply. Using a • Rail-to-Rail Output rail-to-rail output, the INA826 is well-suited for low voltage operation from a 2.7 V single supply as well • Supply Current: 200 µA as dual supplies up to ±18 V. • Supply Range: Additional circuitry protects the inputs against – Single Supply: +2.7 V to +36 V overvoltage of up to ±40 V beyond the power – Dual Supply: ±1.35 V to ±18 V supplies by limiting the input currents to less than • Specified Temperature Range: 8 mA. –40°C to +125°C The INA826 is available in SO-8, MSOP-8, and tiny • Packages: MSOP-8, SO-8 and DFN-8 3-mm × 3-mm DFN-8 surface-mount packages. All versions are specified for the –40°C to +125°C APPLICATIONS temperature range. • Industrial Process Controls RELATED PRODUCTS • Circuit Breakers DEVICE DESCRIPTION • Battery Testers 25-µV VOS, 0.1 µV/°C VOS drift, 1.8-V to 5-V, RRO, INA333 50-µA IQ, chopper-stabilized INA • ECG Amplifiers 20-mV to ±10-V programmable gain IA with 3-V or • Power Automation PGA280 5-V differential output; analog supply up to ±18 V • Medical Instrumentation G = 0.2 V differential amplifier for ±10-V to 3-V and INA159 • Portable Instrumentation 5-V conversion Precision programmable gain op amp with SPI™ PGA112 interface 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 SPI is a trademark of Motorola. 3 PhotoMOS is a registered trademark of Panasonic Electric Works Europe AG. 4 All other trademarks are the property of their respective owners.
