Remote Half Bridge Digitizer Platinum RTD with Noise Suppression on Reference

May 27th 1999
The LTC2414/LTC2418 are 8-/16-channel (4-/8-differential) micropower 24-bit ΔΣ analog-to-digital converters. They operate from 2.7V to 5.5V and include an integrated oscillator, 2ppm INL and 0.2ppm RMS noise. They use delta-sigma technology and provide single cycle settling time for multiplexed applications. Through a single ...

Full-Bridge Amplification Using a Single Amplifier

May 27th 1999
This example shows a single amplifier being used to produce single-ended gain. This topology is best used in applications where the gain setting resistor can be made to match the temperature coefficient of the strain gauges. If the bridge is composed of precision resistors, with only one or two variable elements, the reference ...

Relative Humidity Sensor Digitizer-Charge Pump Based

Jul 15th 1998
Hygrometer Digitizer Has 0.3% Accuracy, Although Sensor Must Float Off-Ground. Humidity Sensor Determines Charge Delivered to A1 Integrator During Each Charge Pump Cycle. Resultant A1 Output Ramp Is Reset by Level Triggered C1 via Q1. Output Frequency, Taken at C1, Varies with Humidity ...

Measuring Seven RTD Temperatures with One Reference Resistor and One Reference Current

Jun 25th 1997
The LTC2408 is 8-channel 2.7V to 5.5V micropower 24-bit A/D converters with an integrated oscillator, 4ppm INL and 0.3ppm RMS noise. They use delta-sigma technology and provide single cycle digital filter settling time (no latency delay) for multiplexed applications. The first conversion after the channel is changed is always ...

Humidty Sensor To Data Aquisition System Interface

Jan 1st 1987
The circuit shown in the schematic features zero drift operational amplifiers (LTC1250 and LTC1050) and a precision instrumentation switched capacitor block (LTC1043). This design will maintain excellent DC accuracy down to microvolt levels. This method was chosen over the use of a true RMS-to-DC or log converter because of ...
