Low-voltage Precision Op Amps Target Sensor Measurement

Fri, 02/04/2011 - 6:29am
low voltage op ampsTexas Instruments Incorporated expanded its 1.8-V precision operational amplifier (op amp) portfolio with a new line for low-noise, high-impedance sensor measurement. The first product in the OPAx320 family, the two-channel OPA2320, provides 20 MHz of gain bandwidth and 0.2 pA input bias current (Ib) to enable high accuracy and dynamic range for high-impedance optical and chemical sensor front ends, programmable logic controllers, motor control loops, and test and measurement equipment. The OPAx320 family features a maximum input bias current of 0.9 pA to support high-impedance sensor signal conditioning, and it provides precision with zero crossover distortion, delivering a maximum offset voltage of 150 uV, high common mode rejection rate of 114 dB and rail-to-rail input/output to drive low-power, successive approximation (SAR) analog-to-digital converters (ADCs),
