| General Description

The ZJA3678 and ZJA3679 are general-purpose difference amplifiers with the gain of 0.5 or 2 intended for precision signal conditioning in power critical applications that require both high performance and low power. They provide exceptional common-mode rejection ratio (98 dB min.) and 800 kHz bandwidth. The common-mode range of the amplifier extends to almost triple the supply voltage (for G = 0.5), making the amplifiers ideal for single-supply applications that require a high common-mode voltage range. The internal resistors and ESD circuitry at the inputs also provide overvoltage protection to the op amp.

Their unique design enables the ZJA3678 and ZJA3679 to with stand ±65 V during power-up and power-down, protecting the entire system. Additionally, on-chip over-temperature protection (OTP) ensures reliable operation under harsh environments.

The ZJA3678/9 operate on single supplies (2.7 V to 36 V) or dual supplies (±1.35 V to ±18 V). The quiescent supply current is 330 µA per channel, which is ideal for battery-operated and portable systems.

The ZJA3678 is available in 8-lead MSOP and SOIC packages, and the ZJA3679 is offered in a 14-lead SOIC package. Both are specified for performance over the temperature range of   -40 °C to +125 °C and are fully RoHS and MSL-1 compliant.
