PRODUCTION DATA. OPA197, OPA2197, OPA4197 SBOS737C – JANUARY 2016 – REVISED MARCH 2018 OPAx197 36-V, Precision, Rail-to-Rail Input/Output, Low Offset Voltage, Operational Amplifiers 1 1 Features 1 • Low Offset Voltage: ±100 µV (Maximum) • Low Offset Voltage Drift: ±2.5 µV/°C (Maximum) • Low Noise: 5.5 nV/ √Hz at 1 kHz • High Common-Mode Rejection: 120 dB (Minimum) • Low Bias Current: ±5 pA (Typical) • Rail-to-Rail Input and Output • Wide Bandwidth: 10-MHz GBW • High Slew Rate: 20 V/µs • Low Quiescent Current: 1 mA per Amplifier (Typical) • Wide Supply: ±2.25 V to ±18 V, +4.5 V to +36 V • EMI- and RFI-Filtered Inputs • Differential Input Voltage Range to Supply Rail • High Capacitive Load Drive Capability: 1 nF • Industry Standard Packages: – Single in SOIC-8, SOT-5, and VSSOP-8 – Dual in SOIC-8 and VSSOP-8 – Quad in SOIC-14 and TSSOP-14 2 Applications • Multiplexed Data-Acquisition Systems • Test and Measurement Equipment • High-Resolution ADC Driver Amplifiers • SAR ADC Reference Buffers • Programmable Logic Controllers • High-Side and Low-Side Current Sensing • High Precision Comparators 3 Description The OPAx197 family (OPA197, OPA2197, and OPA4197) is a new generation of 36-V operational amplifiers. These devices offer outstanding dc precision and ac performance, including rail-to-rail input/output, low offset (±25 µV, typical), low offset drift (±0.25 µV/°C, typ), and 10-MHz bandwidth. Unique features such as differential input-voltage range to the supply rail, high output current (±65 mA), high capacitive load drive of up to 1 nF, and high slew rate (20 V/µs) make the OPA197 a robust, high- performance operational amplifier for high-voltage, industrial applications. The OPA197 family of op amps is available in standard packages and is specified from –40°C to +125°C.
