TI ADS1255IDBR

2430k1，2差分，单端5V1.8V ~ 3.6V-40°C ~ 85°C

Overview

The ADS1255IDBR is an extremely low-noise 24-bit Analog-to-digital Converter (ADC) provides complete high-resolution measurement solutions for the most demanding applications. The converter is comprised of a 4th-order, delta-sigma (ΔΣ) modulator followed by a programmable digital filter. A flexible input multiplexer handles differential or single-ended signals and includes circuitry to verify the integrity of the external sensor connected to the inputs. The selectable input buffer greatly increases the input impedance and the low-noise programmable gain amplifier (PGA) provides gains from 1 to 64 in binary steps. The programmable filter allows the user to optimize between resolution of up to 23-bit noise-free and data rate of up to 30kSPS. The converters offer fast channel cycling for measuring multiplexed inputs and can also perform one-shot conversions that settle in just a single cycle.
