OPA1688

SBOS724A – SEPTEMBER 2015 – REVISED JUNE 2022

OPA1688 36-V, Single-Supply, 10-MHz, Rail-to-Rail Output,

SoundPlus™ Audio Operational Amplifier

1 Features

3 Description

•

THD+N, 50 mW, 32 Ω, 1 kHz, –109 dB

Wide supply range:

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.

– 4.5 V to 36 V, ±2.25 V to ±18 V

Low offset voltage: ±0.25 mV

Low offset drift: ±0.5 µV/°C

Gain bandwidth: 10 MHz

Low input bias current: ±10 pA

Low quiescent current: 1.6 mA per amplifier

Low noise: 8 nV/√Hz

EMI- and RFI-filtered inputs

Input range includes negative supply

Input range operates to positive supply

Rail-to-rail output

High common-mode rejection: 120 dB

Packages:

•

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.

– Industry-standard SOIC-8

– micro WSON-8

2 Applications

•

Professional microphones and wireless systems

Professional audio mixer and control surface

Guitar amp and other music instrument amps

A/V receiver

Bookshelf stereo system

Professional audio amplifier (rack mount)

DJ equipment

The OPA1688 is specified from –40°C to +85°C.
