PRODUCT DESCRIPTION

The AD537 is a monolithic V-F converter consisting of an input

amplifier, a precision oscillator system, an accurate internal ref-

erence 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 over-

all 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-to-

frequency 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.

*Protected by Patent Nos. 3,887,963 and RE 30,586.
