RS1473

14-Bit, 2 MSPS, Dual-Channel, Single-Ended

Analog-to-Digital Converters

1 FEATURES

3 DESCRIPTIONS

The RS1473 is a 14-bit, 2MSPS analog-to-digital

converter (ADC) that offers Single-Ended inputs. The

device operates at a 2MSPS sample rate with a standard

16 clock data frame. The device includes a two-channel

•

Sample Rate: 2 MSPS

INL 2.5 LSB (MAX)

Wide Supply Range:

Analog: 2.7 V to 5.25 V

Digital: 1.65 V to AVDD

14-Bit No Missing Code Resolution

Auto Power-Down at Lower Speeds

Two Single-Ended Inputs

Operating Temperature Range -40 °C to

125 °C

input multiplexer and

low-power successive

approximation register (SAR) ADC with an inherent

sample-and-hold (S/H) input stage.

•

The RS1473 supports a wide analog supply range that

allows the full-scale input range to extend to 5 V single-

ended. A simple SPI, with a digital supply that can

operate as low as 1.65 V, allows for easy interfacing to a

wide variety of digital controllers. Automatic power-

down can be enabled when operating at slower speeds

to dramatically reduce power consumption.
