The AD600/AD602 are dual channel, low noise, variable gain amplifiers. The AD600 has a gain range of 0 to 40 dB and the AD602 has a gain range of -10 to 30 dB. They feature accurate absolute gain, low input noise, low distortion, high bandwidth, stable group delay and low power.
The AD600 and AD602 are dual‑channel, low‑noise, wideband variable‑gain amplifiers optimized for ultrasound imaging but suitable for any application requiring precise gain, low distortion and wide bandwidth. Each channel provides independent gain control with a linear dB response: 0 dB to 40 dB for the AD600 and –10 dB to +30 dB for the AD602.
The devices feature a proprietary X‑AMP architecture, a seven‑stage R‑2R input attenuator, differential gain‑control interfaces (32 dB/V scaling), and TTL/CMOS‑compatible signal‑gating inputs. They are offered in multiple temperature‑grade packages (‑40 °C to +85 °C, 0 °C to 70 °C, –55 °C to +125 °C) and meet MIL‑STD‑883 for the S‑grade versions. This manual is written in Chinese.

The AD600 provides a gain range from 0 dB to 40 dB.
Both devices have an input noise spectral density of 1.4 nV/√Hz.
The amplifiers can drive up to ±2.5 V into a 500 Ω load, which corresponds to a peak output current of about 5 mA.
