Overview
The AD600JRZ-RL, produced by Analog Devices Inc., is a dual-channel, low noise, wideband variable gain amplifier. This component is part of the AD600 series, which is optimized for applications requiring precise gain control, low noise, and wide bandwidth. The AD600 is particularly suited for use in ultrasound imaging systems but is versatile enough to be used in various other applications demanding high performance.

Key Features
- Dual-Channel Operation: Each amplifier section operates independently, providing a gain range of 0 dB to +40 dB.
- Low Noise and Distortion: The AD600 features an input noise spectral density of 1.4 nV/√Hz and a total harmonic distortion of -60 dBc for a ±1 V sinusoidal output at 10 MHz.
- Wide Bandwidth: The -3 dB bandwidth is nominally 35 MHz, essentially independent of the gain setting.
- Signal Gating: Each channel has an independent gating facility that can block signal transmission and set the DC output level to within a few millivolts of the output ground.
- TTL- and CMOS-Compatible Logic Inputs: The gating control inputs are compatible with both TTL and CMOS logic levels.
- High Accuracy Gain Control: The gain-control interfaces are fully differential with a scale factor of 32 dB/V, ensuring accurate and stable gain settings.
