Low-noise (7nV/ √Hz) and high- • Low Noise: 7nV/ √Hz at 10kHz speed operation also make them well-suited for • Wide Bandwidth: 20MHz driving sampling analog-to-digital converters (ADCs). • Slew Rate: 10V/ μs Other applications include signal conditioning and sensor amplification. • Quiescent Current: 1.45mA/ch • Single-Supply Voltage Range: 1.8V to 5.5V The OPA320 features a linear input stage with zero- crossover distortion that delivers excellent common- • OPA320S, OPA2320S: mode rejection ratio (CMRR) of typically 114dB over – IQ in Shutdown Mode: 0.1μA the full input range. The input common-mode range • Unity-Gain Stable extends 100mV beyond the negative and positive supply rails. The output voltage typically swings within • Small Packages: 10mV of the rails. – SOT23, MSOP, DFN In addition, the OPAx320 have a wide supply voltage range from 1.8V to 5.5V with excellent PSRR (106dB) APPLICATIONS over the entire supply range, making them suitable • High-Z Sensor Signal Conditioning for precision, low-power applications that run directly • Transimpedance Amplifiers from batteries without regulation. • Test and Measurement Equipment The OPA320 (single version) is available in a SOT23- • Programmable Logic Controllers (PLCs) 5 package; the OPA320S shut-down single version is available in an SOT23-6 package. The dual OPA2320 • Motor Control Loops is offered in SO-8, MSOP-8, and DFN-8 packages, • Communications and the OPA2320S (dual with shut-down) in an • Input/Output ADC/DAC Buffers MSOP-10 package. • Active Filters 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 FilterPro is a trademark of Texas Instruments Incorporated. 3 All other trademarks are the property of their respective owners.
