AD8337 DC-Coupled VGA

The AD8337 is a low noise, single-ended, linear-in-dB, generalpurpose, variable gain amplifier (VGA) usable at frequencies from dc to 100 MHz; the *3 dB bandwidth is 280 MHz. Excellent bandwidth uniformity across the entire gain range and low output referred noise make the AD8337 ideal for g.

AD8337 Features

* Low noise Voltage noise = 2.2 nV/√Hz Current noise = 4.8 pA/√Hz (positive input) Wide bandwidth (

* 3 dB) = 280 MHz Nominal gain range: 0 dB to 24 dB (preamp gain = 6 dB) Gain scaling: 19.7 dB/V DC-coupled Single-ended input and output High speed uncommitted op amp input Supplies: +5 V, ±2.5 V
