| General Description

The ZJA3676/ZJA3677 are general-purpose, unity-gain difference amplifiers intended for precision signal conditioning in power critical applications that require both high performance and low power. They provide exceptional 104 dB common-mode rejection ratio (CMRR) and 500 kHz bandwidth while amplifying signals almost double the supply rails. They are trimmed for gain drift better than 0.3 ppm/°C and high CMRR.

Their unique design enables the ZJA3676 and ZJA3677 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 ZJA3676/7 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 ZJA3676 is available in 8-lead MSOP and SOIC packages, and the ZJA3677 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.
