Description for the ADS1232

The ADS1232 and ADS1234 (ADS123x) are precision, 24-bit, analog-to-digital converters (ADCs). With a low-noise programmable gain amplifier (PGA), a precision delta-sigma ADC, and internal oscillator, the ADS123x provide a complete front-end solution for bridge sensor applications including weigh scales, strain gauges, and pressure sensors.

An input multiplexer (MUX) accepts either two (ADS1232) or four (ADS1234) differential inputs. The ADS1232 also includes a temperature sensor to monitor ambient temperature. The low-noise PGA has a selectable gain of 1, 2, 64, or 128, supporting a full-scale differential input of ±2.5 V, ±1.25 V, ±39 mV, or ±19.5 mV.

The delta-sigma ADC provides a maximum of 23.5-bits effective resolution, and supports two data rates: 10 SPS (providing 50-Hz and 60-Hz rejection) and 80 SPS. The ADS123x can be clocked externally using an oscillator or a crystal, or by the internal oscillator.

Offset calibration is performed on-demand, and the ADS123x can be put in a low-power standby mode or shut off completely in power-down mode. The ADS123x are operated through simple pin-driven control—there are no digital registers to program.

Data are output over a two-wire serial interface that connects directly to the MSP430 and other microcontrollers.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
