HI7191IPZ

The Intersil HI7191IPZ is a monolithic, high-precision, 24-bit Sigma Delta Analog to Digital Converter designed for demanding applications. It operates from ±5V analog and digital supplies, offering flexibility and performance with fully differential signal and reference inputs.

Key electrical specifications include a resolution of 24 bits, a maximum conversion rate of 2kSPS, and an Integral Non-Linearity (INL) of 0.005%FS. The device features an internal Programmable Gain Instrumentation Amplifier (PGIA) with gains from 1 to 128, eliminating the need for external pre-amplifiers. An auto-calibrate function removes offset and gain errors, while an on-board digital filter provides over 120dB of 60/50Hz noise rejection.

This ADC is housed in a 20-lead PDIP package, suitable for through-hole mounting. It operates within an environmental temperature range of -40°C to 85°C and has a low power consumption of 15mW. The HI7191IPZ includes a serial I/O port compatible with SPI and SSR protocols, offering user control over calibration, gain, and other features.

Applications for the HI7191IPZ include high-accuracy measurement systems where precise analog-to-digital conversion is critical. Its robust design and integrated features make it a suitable choice for instrumentation and data acquisition systems requiring high resolution and noise immunity.
