Product Description:
The ADS1261BIRHBT is a precision 40kSPS ΔΣ analog-to-digital converter (ADC) with a programmable gain amplifier (PGA). The device also contains a precision voltage reference and internal fault monitor. These sensor-enabled ADCs provide high-precision single-chip solutions for the most demanding measurements, including weighing scales and resistive temperature detectors (RTDS).
The ADC includes an input signal multiplexer, a low-noise PGA (providing a gain of 1 to 128), a 4-bit ΔΣ modulator, a precision voltage reference, and a programmable digital filter.
The high impedance PGA input (1GΩ) reduces measurement errors caused by sensor loads. The ADS1261 supports five differential inputs or ten single-ended inputs. Integrated current source simplifies RTD measurement.
