AD600/AD602 are dual-channel, low noise, wideband variable gain amplifiers with linear dB gain response and 2 gain ranges. They feature accurate absolute gain, low input noise, low distortion, high bandwidth, and stable group delay. These products are suitable for ultrasound imaging systems, high-performance audio and RF AGC systems, signal measurement, and other applications.
The AD600/AD602 are dual‑channel, low‑noise, wideband variable‑gain amplifiers optimized for ultrasound imaging but suitable for any application requiring precise gain, low noise, and high bandwidth. Each channel provides independent gain control and a signal‑gating function, and the devices can drive 100 Ω loads with low distortion.
The datasheet lists electrical specifications such as a 1.4 nV/VHz input‑noise spectral density, –3 dB bandwidth of 35 MHz, total harmonic distortion of –60 dBc at +1 V output, and a maximum power consumption of 125 mW per amplifier. Various package options and temperature grades are covered, along with pin configurations and typical performance curves.
| Input Noise Spectral Density | 1.4 nV/VHz |
|---|---|
| Gain Range (AD600) | 0 dB to 40 dB |
