AD7740KRMZ-REEL7:  3 V/5 V Low Power, Synchronous Voltage-to-Frequency Converter

The AD7740 is the world's smallest, lowest-cost, 12-Bit accurate VFC.

Since this is a synchronous converter, the output frequency is related to the fixed master clock frequency so temperature stability is much improved over asynchronous VFCs. With a 1 MHz input clock frequency, the FS output frequency is 900 kHz. The voltage reference input can be tied to the supply, if required.

Historically the primary applications for VFCs have been either to implement low cost A/D conversion or to achieve simple isolation.

The AD7740 is being offered in an 8-pin MicroSOIC package plus an 8-lead SOT-23 package. The SOT-packaged devices are only available on T&R. Two operating temperature ranges are available; from 0°C to +85°C and from -40°C to +105°C
