Texas Instruments OPA1688 SoundPlus™ Audio Amplifiers are 36V, single-supply, low-noise operational amplifiers capable of operating on supplies ranging from 4.5V (±2.25V) to 36V (±18V). These high-voltage audio operational amplifiers, 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 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 dual and quad versions all have identical specifications for maximum design flexibility. 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.
