OPA4172-Q1 (ACTIVE)

Automotive 36-V, Single-Supply, 10-MHz, Rail-to-Rail Output, Operational Amplifier

 

Description

The OPA2172-Q1 and OPA4172-Q1 (OPAx172-Q1) are a family of 36-V, single-supply, low-noise operational amplifiers capable of operating on supplies ranging from 4.5 V (±2.25 V) to 36 V
(±18 V). The OPAx172-Q1 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 dual and quad versions all have identical specifications for maximum design flexibility.

Unlike most op amps that are specified at only one supply voltage, the OPAx172-Q1 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.

The OPAx172-Q1 series of op amps are specified from –40°C to +125°C.
