The Analog Devices AD537SD is a high-performance Voltage to Frequency (V/F) converter IC designed for precision signal conversion. It offers a wide frequency range of up to 150 kHz, with rated performance at 100 kHz. The device boasts excellent linearity of ±0.05% and a full-scale calibration error of ±5% max.
Key electrical characteristics include a low input bias current of 100 nA and a high input resistance of 250 MΩ. The voltage reference output is 1.00 Volt ± 5% max, with a temperature coefficient of 50 ppm/°C. The output interface is an open collector, providing a symmetrical square wave with an output sink current of 20 mA min in logic '0'.
The AD537SD operates from a single supply voltage of 4.5 V to 36 V or a dual supply of ±5 V to ±18 V, with a typical quiescent current of 1.2 mA. It is rated for operation within a temperature range of 0°C to +70°C. The component is housed in a 14-CDIP (0.300", 7.62mm) through-hole package, making it suitable for various industrial and electronic applications requiring accurate voltage-to-frequency conversion.
