Ultrasound Variable-Gain Amplifier  
MAX2037  
General Description  
Features  
The MAX2037 8-channel variable-gain amplifier (VGA)  
is designed for high linearity, high dynamic range, and  
low-noise performance targeting ultrasound imaging  
and Doppler applications. Each amplifier features dif-  
ferential inputs and outputs and a total gain range of  
typically 42dB. In addition, the VGAs offer very low out-  
put-referred noise performance suitable for interfacing  
with 12-bit ADCs.  
♦ 8-Channel Configuration  
♦ High Integration for Ultrasound Imaging  
Applications  
♦ Pin Compatible with the MAX2038 Ultrasound  
VGA Plus CW Doppler Beamformer  
♦ Maximum Gain, Gain Range, and Output-Referred  
Noise Optimized for Interfacing with 12-Bit ADCs  
Maximum Gain of 29.5dB  
The MAX2037 VGA is optimized for less than 0.2ꢀdB  
absolute gain error to ensure minimal channel-to-chan-  
nel ultrasound beamforming focus error. The device’s  
differential outputs are designed to directly drive ultra-  
sound ADCs through an external passive anti-aliasing  
filter. A switchable clamp is also provided at each ampli-  
fier’s outputs to limit the output signals, thereby prevent-  
ing ADC overdrive or saturation.

The MAX2037 operates from a +ꢀ.0V power supply,  
consuming only 120mW/channel. The device is avail-  
able in a 100-pin TQFP package with an exposed pad-  
dle. Electrical performance is guaranteed over a 0°C to  
+70°C temperature range.
