The AD693AD from Analog Devices is a monolithic signal conditioning circuit that functions as a loop-powered 4-20 mA sensor transmitter. It is designed to accept low-level inputs from various transducers and control a standard two-wire current loop. The device includes an on-chip voltage reference and an auxiliary amplifier, providing up to 3.5 mA of excitation current in loop-powered mode.
Precalibrated input spans of 30 mV or 60 mV can be set via pin strapping, with other spans achievable using external resistors. The output span and zero are also configurable through pin strapping, supporting standard ranges such as 4-20 mA, 0-20 mA, and 12 ± 8 mA. The AD693AD boasts high accuracy due to active laser trimming of its thin-film resistors, with total unadjusted error less than 0.5% of full scale at +25 °C and less than 0.75% over the industrial temperature range.
This sensor transmitter is suitable for applications in process control and factory automation. It is available in 20-pin DIP, Cerdip, and LCCC packages and is specified for operation across the industrial temperature range of -40°C to +85°C. An optional external pass transistor can be used to further reduce self-heating errors.
