Low Quiescent Current: 1.6 mA per Amplifier
Low Noise: 6 nV/√Hz
bandwidth, noise, and power options to meet the
needs of a wide variety of applications. The OPAx172
are available in micropackages and offer low offset,
drift, and quiescent current. These devices also offer
wide bandwidth, fast slew rate, and high output
current drive capability. The single, dual, and quad
versions all have identical specifications for maximum
design flexibility.
EMI and RFI Filtered Inputs
Input Range Includes the Negative Supply
Input Range Operates to Positive Supply
Rail-to-Rail Output
Unlike most op amps, which are specified at only one
supply voltage, the OPAx172 family is specified from
+4.5 V to +36 V. Input signals beyond the supply rails
do not cause phase reversal. The input can operate
100 mV below the negative rail and within 2 V of the
top rail during normal operation. Note that these
devices can operate with full rail-to-rail input 100 mV
beyond the top rail, but with reduced performance
within 2 V of the top rail.
High Common-Mode Rejection: 120 dB
