A Collection of Differential to Single-Ended Signal Conditioning Circuits for Use with the LTC2400, a 24-Bit No Latency ΔΣADC in an SO-8


A Collection of Differential to Single-Ended Signal Conditioning Circuits for Use with the LTC2400, a 24-Bit No Latency ΔΣADC in an SO-8

This document describes six low power differential-to-single-ended signal conditioning circuits for the LTC2400 No Latency ΔΣ™ 24-bit ADC. These circuits offer the customer a number of choices for conditioning differential input signals as low as 5mV to as high as ±2.5V, as well as operation on a single 5V or ±5V supplies. Each circuit description also covers circuit design and implementation techniques that can help preserve the LTC2400's inherently high effective resolution. Publication concludes with two circuits for digitizing temperature when using an RTD or Type S thermocouple.
