Product Overview
AD693 is a monolithic signal conditioning circuit which accepts low-level inputs from a variety of transducers to control a standard 4 to 20mA, two-wire current loop. An on-chip voltage reference and auxiliary amplifier are provided for transducer excitation up to 3.5mA of excitation current is available when the device is operated in the loop powered mode. Alternatively, the device may be locally powered for three-wire applications when 0 to 20mA operation is desired.
- Instrumentation amplifier front end
- Loop powered operation
- Independently adjustable output span and zero
- Precalibrated output spans of 12 ±8mA bipolar
- Precalibrated 100V RTD interface
- Uncommitted auxiliary amp for extra flexibility
- Optional external pass transistor to reduce self-heating errors
- ±5.6µV/V power supply rejection and ±30µV/V common-mode rejection (RTI)
- 20 lead CDIP package
- Operating temperature range from -40°C to 85°C
