Integrated Circuit Voltage-to-Frequency Converter

 

 

Description:

 

The AD537 is a monolithic V-F converter consisting of an input amplifier, a precision oscillator system, an accurate internal reference generator and a high current output stage. Only a single external RC network is required to set up any full-scale (F.S.) frequency up to 100 kHz and any F.S. input voltage up to ±30 V. Linearity error is as low as ±0.05% for 10 kHz F.S., and operation is guaranteed over an 80 dB dynamic range. The overall temperature coefficient (excluding the effects of external components) is typically ±30 ppm/°C. The AD537 operates from a single supply of 5 V to 36 V and consumes only 1.2 mA quiescent current.

A temperature-proportional output, scaled to 1.00 mV/K, enables the circuit to be used as a reliable temperature-tofrequency converter; in combination with the fixed reference output of 1.00 V, offset scales such as 0°C or 0°F can be generated.

The low drift (1 µV/°C typ) input amplifier allows operation directly from small signals (e.g., thermocouples or strain gages) while offering a high (250 MΩ) input resistance. Unlike most V–F converters, the AD537 provides a square-wave output, and can drive up to 12 TTL loads, LEDs, very long cables, etc.

The excellent temperature characteristics and long-term stability of the AD537 are guaranteed by the primary bandgap reference generator and the low T.C. silicon chromium thin film resistors used throughout.

The device is available in either a 14-lead ceramic DIP or a 10-lead metal can; both are hermetically sealed packages.

The AD537 is available in three performance/temperature grades; the J and K grades are specified for operation over the 0°C to +70°C range while the AD537S is specified for operation over the extended temperature range, –55°C to +125°C.
