16-Bit, 400KSPS, 4-Channel Low-Distortion, Multiplexed Data Acquisition System for High-Voltage Inputs

This TI verified design implements a 16-bit differential 4-channel multiplexed data acquisition system at 400 KSPS throughput for high voltage differential inputs for ±20 V (40 Vpk-pk) industrial applications. The circuit is implemented with a 16-bit successive approximation register (SAR) analog-to-digital converter (ADC), a precision high-voltage signal conditioning front end, and a 4-channel differential multiplexer (MUX). This design details the use of the OPA192 and OPA140 to optimize a precision high-voltage front-end driver circuit to achieve the excellent dynamic performance of the ADS8864 .

Ultra-small 1W, 12V-36V isolated power supply reference design for analog programmable logic controller modules

Analog input and output modules are standard components of programmable logic controllers (PLCs) or distributed control systems (DCS). In these modules, the increasing number of channels per module and the thinner and thinner modules present design challenges for isolated power supplies. All designers facing these challenges will benefit from the TIDA-00237 as its total design size is less than 2.54x2.54mm and its height is less than 5mm. It uses a flyback approach, which means no optocoupler feedback is required, and has a wide input voltage range of 12V-36V. This design provides +/-15V and 5V isolated low-noise outputs, making it ideal for driving data converters or analog front ends.

Power chopper dimming controls boost LED driver efficiency and maintains minimum inrush current

This LED driver reference design drives a 700mA constant current to a single string of LEDs with forward voltages up to 60V. The design allows PWM dimming based on supply chopping. The input power supply is chopped on and off at 300Hz to 1kHz frequency to achieve LED brightness control. The driver uses a fixed-frequency boost converter, controlled by the MAX16834 LED driver. This unique reference design limits the input inrush current to negligible levels without compromising either the input or output filtering. Design schematics and test results are provided.
