Datasheet
The MAX2055 is a high-performance, digitally controlled, variable-gain, differential analog-to-digital converter (ADC) driver/amplifier (DVGA) designed for use from 30MHz to 300MHz in base station receivers. The device integrates a digitally controlled attenuator and a high-linearity single-ended-to-differential output amplifier, which can either eliminate an external transformer, or can improve the even-order distortion performance of a transformer-coupled circuit, thus relaxing the requirements of the anti-alias filter preceding an ADC. Targeted for ADC driver applications to adjust gain either dynamically or as a one-time channel gain setting, the MAX2055 is ideal for applications requiring high performance. The attenuator provides 23dB of attenuation range with ±0.2dB accuracy. The MAX2055 is available in a thermally enhanced 20-pin TSSOP-EP package and operates over the -40°C to +85°C temperature range. Application areas include cellular base stations, PHS/PAS infrastructure receiver gain control, broadband systems, automatic test equipment, terrestrial links, and high-performance ADC drivers.
