Description
General part information
OPA862 Series
The OPA862 is a single-ended to differential analog-to-digital converter (ADC) driver with high input impedance for directly interfacing with sensors. The device only consumes 3.1-mA quiescent current for an output-referred noise density of 8.3 nV/√Hzin a gain of 2-V/V configuration. A fully differential amplifier configured in a gain of 1 V/V with 1-kΩ resistors must be less than 1 nV/√Hzto achieve the OPA862 equivalent output-referred noise density of 8.3 nV/√Hz. The OPA862 can be configured for other gains using external resistors. The device has a large gain-bandwidth product of 400 MHz and a slew rate of 140 V/µs. This yields exceptional linearity and fast-settling, 18-bit performance over comparable single-ended-to-differential ADC drivers. The device includes a reference input pin for setting the output common-mode voltage.
The OPA862 is fully characterized to operate over a wide supply range of 3 V to 12.6 V, and features a rail-to-rail output stage. The device is fabricated using Texas Instruments’ proprietary, high-speed, silicon-germanium (SiGe) process and achieves exceptional distortion performance for 18-bit systems. The device includes a disable mode that consumes only 12-µA quiescent current in power-down state.
The OPA862 is rated to work over the extended industrial temperature range of –40°C to +125°C.
