The OPA1688 36-V, single-supply, low-noise SoundPlus™ audio operational amplifier is capable of operating on supplies ranging from 4.5 V (±2.25 V) to 36 V (±18 V). This latest addition of a high-voltage audio operational amplifier in conjunction with the OPA16xx devices provide a family of bandwidth, noise, and power options to meet the needs of a wide variety of applications. The OPA1688 is available in a WSON micropackage, and offers low offset, drift, and quiescent current. This device also offers wide bandwidth, fast slew rate, and high output current drive capability.
Unlike most op amps that are specified at only one supply voltage, the OPA1688 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 this device 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 OPA1688 is specified from –40°C to +85°C.
