MAX11901
EVALUATION KIT AVAILABLE
16-Bit, 1.6Msps, Low-Power,
Fully Differential SAR ADC
General Description
The MAX11901 is a 16-bit, 1.6Msps, single-channel, fully
differential SAR ADC with internal reference buffers. The
MAX11901 provides excellent static and dynamic perfor-
mance with best-in-class power consumption that directly
scales with throughput. The device has a unipolar differ-
ential ±VREF input range. Supplies include a 3.3V supply
for the reference buffers, a 1.8V analog supply, a 1.8V
digital supply, and a 1.5V to 3.6V digital interface supply.
This ADC achieves 95.2dB SNR and -115dB THD, guar-
antees 16-bit resolution with no-missing codes and 0.5
LSB INL (max).
The MAX11901 communicates data using a SPI-
compatible serial interface. The MAX11901 is offered in a
20-pin, 4mm x 4mm, TQFN package and is specified over
the -40°C to +85°C operating temperature range.
