TI ADC12DL040CIVSX/NOPB

The ADC12DL040 is a dual-channel, low-power CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at a rate of 40 mega samples per second (MSPS). The converter employs a differential pipeline architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption while delivering excellent dynamic performance. It also features a 250 MHz full-power bandwidth. The ADC12DL040 operates from a single +3.0V supply and consumes only 210 mW of power at 40 MSPS (including reference current). The device includes a power-down feature that reduces power consumption to 36 mW. The differential inputs provide a full-scale differential input swing equal to 2× VREF and support single-ended inputs. Full utilization of the differential inputs is recommended for optimal performance. The digital outputs of both ADCs are accessible via a single multiplexed 12-bit bus or separate buses. Duty cycle stabilization and output data format are selectable via tri-state function pins; output data can be configured as offset binary or two's complement. To facilitate interfacing with low-voltage systems, the digital output driver supply pin of the ADC12DL040 can be connected to a separate supply voltage ranging from +2.4V to the analog supply voltage. The device is available in a 64-pin TQFP package and operates over the industrial temperature range of -40°C to +85°C.
