General Description

q 8 DIFFERENTIAL ANALOG INPUTS q 1VPP DIFFERENTIAL INPUT RANGE q INT/EXT VOLTAGE REFERENCE q ANALOG/DIGITAL SUPPLY: 1.8V q DIGITAL I/O SUPPLY: 1.8V/3.3V q DIFFERENTIAL NONLINEARITY: ±0.4LSB q INTEGRAL NONLINEARITY: ±0.6LSB q SIGNAL-TO-NOISE: 60dB at fIN = 20MHz q POWER DISSIPATION: 500mW q INDIVIDUAL CHANNEL POWER-DOWN q 257-LEAD, 0.8 BALL PITCH, PLASTIC MicroSTAR BGA™ (16mm • 16mm) APPLICATIONS 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.
