Description for the ADS1261

The ADS1260 and ADS1261 (ADS126x) are precision, 40-kSPS, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) that include a programmable gain amplifier (PGA). The devices also include a precision voltage reference and internal fault monitors. The sensor-ready ADCs give a high-accuracy, single-chip solution for the most demanding measurements, for example, weigh scales and resistance temperature detectors (RTDs).

The ADCs contain an input signal multiplexer, a low-noise PGA (with gains from 1 to 128), a 24-bit ΔΣ modulator, a precision voltage reference, and a programmable digital filter.

The high-impedance PGA inputs (1 GΩ) decrease measurement error due to sensor loading. The ADS1260 supports three differential or five single-ended inputs. The ADS1261 supports five differential or ten single-ended inputs. The integrated current sources simplify the measurement of RTDs.

The flexible digital filter is programmable for single-cycle settled conversions, while supplying simultaneous 50-Hz and 60-Hz line cycle rejection. Signal and reference monitors, a temperature sensor, and CRC data verification make data reliability better.

The ADS126x are pin compatible devices given in a 5-mm × 5-mm VQFN package and are specified across the –40°C to +125°C temperature range.

Carrier options

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

A 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.
