Quad Low Noise, Low Cost Variable Gain Amplifier

The AD8335 is a quad Variable Gain Amplifier (VGA) with low noise preamplifier intended for cost and power sensitive applications. AD8335 features four channels with 48 dB gain range; fully differential signal paths; and active input preamplifier matching. The AD8335 has an output gain Switch of 8 dB and separate gain controls for each channel.
The aggregate input referred voltage noise at maximum gain is 1.3 nV/Hz; the preamplifier (PrA) has 1.2 nV/Hz. The PrA has a single-ended to differential gain of 8 (18.06 dB) and a maximum input signal capability is 625 mVPK-PK. Assuming a 20 MHz noise bandwidth (NBW), the Nyquist frequency for a 40 MHz ADC the input SNR is 92 dB. The HILO pin optimizes the output SNR for 10 and 12 bit ADCs with 1 or 2 Vpp full-scale (FS) inputs.
Channels 1 and 2 are enabled through the EN12 pin while channels 3 and 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 pin chip scale (9x9 mm) package for the industrial temperature range of -40C to +85C.
