FEATURES
2 channels with independent gain control Linear in dB gain response 2 gain ranges AD600: 0 dB to 40 dB AD602: –10 dB to +30 dB Accurate absolute gain: ±0.3 dB Low input noise: 1.4 nV/√Hz Low distortion: −60 dBc THD at ±1 V output High bandwidth: dc to 35 MHz (−3 dB) Stable group delay: ±2 ns Low power: 125 mW (maximum) per amplifier Signal gating function for each amplifier Drive high speed ADCs MIL-STD-883-compliant and DESC versions available APPLICATIONS
Ultrasound and sonar time-gain controls High performance audio and RF AGC systems Signal measurement GENERAL DESCRIPTION
The AD600/AD6021 dual-channel, low noise, variable gain amplifiers are optimized for use in ultrasound imaging systems but are applicable to any application requiring precise gain, low noise and distortion, and wide bandwidth. Each independent channel provides a gain of 0 dB to +40 dB in the AD600 and −10 dB to +30 dB in the AD602. However, both products have the same 1.4 nV/√Hz input noise spectral density.
