New Single-supply 10MHz rail-to-rail output operational amplifier

The OPA172, OPA2172 and OPA4172 are members of a new family of 36V, single-supply, low-noise operational amplifiers from Texas Instruments (TI). The devices are capable of operating on supplies ranging from +4.5V (±2.25V) to +36V (±18V). The high-voltage CMOS operational amplifiers, in conjunction with the OPAx171 and OPAx170, provide a family of bandwidth, noise, and power options to meet the needs of a wide variety of applications. The OPAx172 are available in micro packages 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. Unlike many op amps, which are specified at only one supply voltage, the OPAx172 family is specified from +4.5V to +36V. Input signals beyond the supply rails do not cause phase reversal. The input can operate 100mV below the negative rail and within 2V 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 2V of the top rail. The OPAx172 series of op amps are specified from –40C to +125C, says the company.
