SBOS445B – JULY 2008 – REVISED OCTOBER 2008 Micro-Power (50 µA), Zerø-Drift, Rail-to-Rail Out Instrumentation Amplifier 2 • LOW OFFSET VOLTAGE: 25µV (max), G ≥ 100 The INA333 is a low-power, precision instrumentation amplifier offering excellent accuracy. The versatile • LOW DRIFT: 0.1µV/°C, G ≥ 100 3-op amp design, small size, and low power make it • LOW NOISE: 50nV/√Hz, G ≥ 100 ideal for a wide range of portable applications. • HIGH CMRR: 100dB (min), G ≥ 10 A single external resistor sets any gain from 1 to • LOW INPUT BIAS CURRENT: 200pA (max) 1000. The INA333 is designed to use an • SUPPLY RANGE: +1.8V to +5.5V industry-standard gain equation: G = 1 + (100k Ω/RG). • INPUT VOLTAGE: (V–) +0.1V to (V+) –0.1V The INA333 provides very low offset voltage (25 µV, • OUTPUT RANGE: (V–) +0.05V to (V+) –0.05V G ≥ 100), excellent offset voltage drift (0.1 µV/°C, G ≥ 100), and high common-mode rejection (100dB • LOW QUIESCENT CURRENT: 50µA at G ≥ 10). It operates with power supplies as low as • OPERATING TEMPERATURE: –40°C to +125°C 1.8V (±0.9V), and quiescent current is only • RFI FILTERED INPUTS 50 µA—ideal for battery-operated systems. Using autocalibration techniques to ensure excellent • MSOP-8 AND DFN-8 PACKAGES precision over the extended industrial temperature range, the INA333 also offers exceptionally low noise density (50nV/ √Hz) that extends down to dc. • BRIDGE AMPLIFIERS The INA333 is available in both MSOP-8 and DFN-8 • ECG AMPLIFIERS surface-mount packages and is specified over the • PRESSURE SENSORS TA = –40°C to +125°C temperature range. • MEDICAL INSTRUMENTATION blank • PORTABLE INSTRUMENTATION • WEIGH SCALES • THERMOCOUPLE AMPLIFIERS • RTD SENSOR AMPLIFIERS • DATA ACQUISITION 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 All trademarks are the property of their respective owners.
