Description
The HI-574A/883 is a complete 12-bit, analog-to-digital converter, including a +10V reference clock, three-state outputs, and a digital interface for microprocessor control. Successive approximation conversion is performed by two monolithic dice housed in a 28-lead package. The bipolar analog die features our dielectric isolation process, which provides enhanced AC performance and freedom from latch-up.

- Application NotePDF 514 KB R34AN0005EU0100 Rev.1.00 Dec 05, 2022AI-generated Summary: The document explains the output data formats for precision SAR ADCs, focusing on unsigned (unipolar) and signed (bipolar) formats. It details how the analog input voltage maps to digital codes for 14-bit resolution devices, including the ISL73141SEH and ISL73148SEH models. The unsigned format encodes input voltage from zero to full scale as positive binary values, while the signed format uses two’s complement encoding to represent bipolar input ranges. Configuration through the iRADAnalyzer software and hardware setup on evaluation boards is described, including how gain settings and common mode voltages affect input ranges and output codes. Tables illustrate the relationship between input voltage, digital codes, and device operation modes.

- Application NotePDF 224 KB an9654 May 05, 1999AI-generated Summary: The document explains the reliability and failure mechanisms of semiconductor parts, focusing on life testing and wearout. It discusses how switching states cause transient current pulses and hot carrier injection, which only occur briefly during switching. Life testing at elevated temperatures accelerates aging to remove infant mortality failures, improving reliability. The failure rate follows a bathtub curve with infant mortality, useful life, and wearout phases, modeled by lognormal and exponential distributions. The Arrhenius equation relates failure rates at different temperatures. Burn-in and life tests reduce early failures without harming intrinsic reliability.
- Application NotePDF 508 KB an9510 Aug 19, 1998AI-generated Summary: The document explains fundamental analog circuit concepts for digital designers, focusing on superposition, Thevenin equivalent circuits, and feedback principles. It details the operation and assumptions of inverting and non-inverting op amps, differential amplifiers, and the use of T networks in feedback paths. The text highlights the importance of feedback in controlling closed-loop gain and stability, and distinguishes between voltage and current feedback op amps, especially in high-frequency applications like video amplifiers.
