Digitally Controlled, Variable-Gain, Differential

ADC Driver/Amplifier

General Description

Features

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.

ꢀ 30MHz to 300MHz Frequency Range

ꢀ Single-Ended-to-Differential Conversion

ꢀ -3dB to +20dB Variable Gain

The device integrates a digitally controlled attenuator

and a high-linearity single-ended-to-differential output

amplifier, which can either eliminate an external trans-

former, or can improve the even-order distortion perfor-

mance 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.

ꢀ 40dBm Output IP3 (at All Gain States and 70MHz)

ꢀ 2nd Harmonic -76dBc

ꢀ 3rd Harmonic -69dBc

ꢀ Noise Figure: 5.8dB at Maximum Gain

ꢀ Digitally Controlled Gain with 1dB Resolution and

0.2dB Accuracy

ꢀ Adjustable Bias Current

The MAX2055 is available in a thermally enhanced 20-

pin TSSOP-EP package and operates over the -40°C to

+85°C temperature range.
