Differential SAR ADC - Maxim Integrated
Description
MAX11960
EVALUATION KIT AVAILABLE
Dual Simultaneous Sampling, 20-Bit, 1Msps, Differential SAR ADC
General Description
The MAX11960 is a 20-bit, 1Msps, dual simultaneous sampling, fully differential SAR ADC with internal reference buffers.
The MAX11960 provides excellent static and dynamic performance with best-in-class power consumption that directly scales with throughput.
The device has a unipolar differential ±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 99dB SNR and -123dB THD, guarantees 20-bit resolution with no-missing codes and 5 LSB INL (max).
The MAX11960 communicates data using a SPIcompatible serial interface.
The MAX11960 is offered in a 32-pin, 5mm x 5mm, TQFN package and is specified over the -40°C to +85°C operating temperature range.
