Not Recommended for New Designs (NRND)

Replaced By ADS7869 – The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device. See the ADS7869 as a functional replacement and upgrade.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

Description

The VECANA01 consists of three 12-bit analog-to-digital converters preceded by five simultaneously operating sample-hold amplifiers, and multiplexers for 10 differential inputs. The ADCs have simultaneous serial outputs for high speed data transfer and data processing.

The VECANA01 also offers a programmable gain amplifier with programmable gains of 1.0V/V, 1.25V/V, 2.5V/V, and 5.0V/V. Channel selection and gain selection are selectable through the serial input control word. The high through put rate is maintained by simultaneously clocking in the 13-bit input control word for the next conversion while the present conversions are clocked out.

The part also contains an 8-bit digital-to-analog converter whose digital input is supplied as part of the input control word.
