MAX2055 Digitally Controlled, Variable-Gain, Differential ADC Driver/Amplifier
The MAX2055 high-performance, digitally controlled, variable-gain, differential Analog-to-digital converter (ADC) driver Amplifier (DVGA) is 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 -40C to +85C temperature range.
