Description

The ADS5121 is a low-power, 8-channel, 10-bit, 40MSPS CMOS Analog-to-Digital Converter (ADC) that operates from a single 1.8V supply, while offering 1.8V and 3.3V digital I/O flexibility. A single-ended input clock is used for simultaneous sampling of up to eight analog differential input channels. The flexible duty cycle adjust circuit (DCASEL) allows the use of a non-50% clock duty cycle. Individual standby pins allow users the ability to power-down any number of ADCs. The internal reference can be bypassed to use an external reference to suit the accuracy and temperature drift requirements of the application. A 10-bit parallel bus on eight channels is provided with 3-state outputs. The speed, resolution, and low power of the ADS5121 make it ideal for applications requiring high-density signal processing in low-power environments. The ADS5121 is characterized for operation from –40°C to +85°C.
