Product details

Description

The AD604 is an ultralow noise, very accurate, dual-channel, linear-in-dB variable gain amplifier (VGA) optimized for timebased variable gain control in ultrasound applications; however, it supports any application requiring low noise, wide bandwidth, variable gain control.

Features

Ultralow input noise at maximum gain 0.80 nV/√Hz, 3.0 pA/√Hz 2 independent linear-in-dB channels Absolute gain range per channel programmable 0 dB to 48 dB (preamplifier gain = 14 dB) through 6 dB to 54 dB (preamplifier gain = 20 dB) ±1.0 dB gain accuracy Bandwidth: 40 MHz (.
3 dB) Input resistance: 300 kΩ Variable gain scaling: 20 dB/V through 40 dB/V Stable gain with temperature and supply variations Single-ended unipolar gain control Power shutdown at lower end of gain control Drive AD.
