www.ti.com SNAS260E – NOVEMBER 2004 – REVISED NOVEMBER 2004 ADC124S051 4 Channel, 200 ksps to 500 ksps, 12-Bit A/D Converter
Check for Samples: ADC124S051 FEATURES DESCRIPTION The ADC124S051 is a low-power, four-channel
CMOS 12-bit analog-to-digital converter with a highspeed serial interface. Unlike the conventional
practice of specifying performance at a single sample
rate only, the ADC124S051 is fully specified over a
sample rate range of 200 ksps to 500 ksps. The
converter is based on a successive-approximation
register architecture with an internal track-and-hold
circuit. It can be configured to accept up to four input
signals at inputs IN1 through IN4. 1 2 Specified Over a Range of Sample Rates
Four Input Channels
Variable Power Management
Single Power Supply with 2.7V -5.25V Range KEY SPECIFICATIONS DNL: +0.7 / -0.4 LSB (typ)
INL: В± 0.5 LSB (typ)
SNR: 72.5 dB (typ)
Power Consumption:
– 3V Supply: 3.0 mW (typ)
– 5V Supply: 10.0 mW (typ) The output serial data is straight binary, and is
compatible with several standards, such as SPIв„ў,
QSPIв„ў, MICROWIRE and many common DSP serial
interfaces.
The ADC124S051 operates with a single supply that …
