Maxim Integrated Products Inc. introduced the MAX2055, which the company says is the industry's first high-performance, digitally controlled, variable-gain, differential analog-to-digital converter (ADC) driver/amplifier (DVGA).

The MAX2055 integrates a digitally controlled attenuator and a high-linearity single-ended-to-differential output amplifier, which can either eliminate an external transformer, or improve the even-order distortion performance of a transformer-coupled circuit, thus relaxing the requirements of the anti-alias filter preceding an ADC.

The MAX2055 is optimized to deliver IF frequencies from 30 MHz to 300 MHz. It is ideal for GSM, DCS/PCS, EDGE, iDEN, PHS, cdma2000, and WB-CDMA multicarrier and single carrier base-station applications.

The MAX2055 delivers 23 dB of gain range with ±0.2 dB accuracy over the full temperature range. OIP3 performance is 40 dBm over the -3 dB to +20 dB gain range.
