General Description
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 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.
The MAX2055 is available in a thermally enhanced 20-
pin TSSOP-EP package and operates over the -40°C to
+85°C temperature range.
