The HI7190IPZ is a 24-bit, high precision sigma-delta analog-to-digital converter (ADC) designed for use in various applications such as process control, industrial weight scales, and laboratory instrumentation. It operates from ±5V supplies and features fully differential signal and reference inputs, enhancing performance and flexibility. The device includes an internal programmable gain instrumentation amplifier (PGIA) with selectable gains from 1 to 128, eliminating the need for external pre-amplifiers. This ADC offers a typical integral non-linearity of 0.0007% and supports full-scale input ranges from 20mV to ±2.5V. It incorporates a user-programmable digital filter that provides over 120dB of noise rejection at 60/50Hz, allowing for fine-tuning of resolution and conversion speed. The HI7190IPZ is compatible with various synchronous transfer formats, including SPI, and features a serial I/O port for communication. Additionally, it includes an on-demand auto-calibration function to correct offset and gain errors. The HI7190IPZ is available in a 20-lead PDIP package and is RoHS compliant, making it suitable for environmentally conscious designs. This product is ideal for engineers seeking a high-performance ADC with integrated features that simplify design and enhance measurement accuracy.
