ISL26104AVZ-T

Analog To Digital Converters (ADC) Overview

The ISL26104AVZ-T is a low-noise, 24-bit Analog-to-Digital Converter (ADC) from the ISL26104 series. It integrates a programmable gain amplifier with gains ranging from 1 to 128 and features four differential, multiplexed inputs. The device utilizes a Sigma-Delta architecture with a third-order modulator, supporting conversion rates from 2.5 Sps to 4 kSps. It operates on an analog supply of 4.75 V to 5.25 V and a digital supply of 2.7 V to 5.25 V. The component provides up to 21.5 bits of noise-free performance at 10 Sps and communicates via a serial interface. It is housed in a Thin Shrink Small Outline Package (TSSOP) and functions within a temperature range of -40°C to +105°C.
