GENERAL DESCRIPTION
The AD8335 is a quad variable gain amplifier (VGA) with
low noise preamplifier intended for cost and power sensitive
applications. Each channel features a gain range of 48 dB, fully
differential signal paths, active input preamplifier matching,
and user-selectable maximum gains of 46 dB and 38 dB.
Individual gain controls are provided for each channel.
The preamplifier (PrA) has a single-ended to differential gain of
×8 (18.06 dB) and accepts input signals ≤625 mV p-p. PrA noise is
1.2 nV/√Hz and the combined input referred voltage noise of
the PrA and VGA is 1.3 nV/√Hz at maximum gain.
Assuming a 20 MHz noise bandwidth (NBW), the Nyquist
frequency for a 40 MHz ADC, the input SNR is 92 dB. The
HLxx pin optimizes the output SNR for 10-bit and 12-bit
ADCs with 1 V p-p or 2 V p-p full-scale (FS) inputs.
Channel 1 and Channel 2 are enabled through the EN12 pin, and
Channel 3 and Channel 4 are enabled through the EN34 pin.
For VGA only applications, the PrAs can be powered down,
significantly reducing power consumption.
The AD8335 is available in a 64-lead lead frame chip scale
package (9 mm × 9 mm) for the industrial temperature range
of 40°C to +85°C.
