AD7740KRMZ, V/F Converter IC 1MHz MSOP

Data Transfer AD7740 is a low-cost, ultra small synchronous voltage-to-frequency converter (VFC). The full-scale output frequency is synchronous with the clock signal on the CLKIN pin. This clock can be generated with the addition of an external crystal (or resonator) or supplied from a CMOS-compatible clock source. The part has a maximum input frequency of 1MHz. For an analogue input signal that goes from 0V to VREF, the output frequency goes from 10% to 90% of fCLKIN. In buffered mode, the part provides a very high input impedance and accepts a range of 0.1V to VDD - 0.2V on the VIN pin. There is also an unbuffered mode of operation that allows VIN to go from -0.15V to VDD + 0.15V. The modes are interchangeable using the BUF pin. It is widely used in application such as isolation of high common-mode voltages, low-cost analogue-to-digital conversion, battery monitoring, automotive sensing etc. • 3V or 5V operation • Low power is 3mW typ • True -150mV capability without charge pump • VREF range is 2.5V to VDD • Internal 2.5V reference • 1MHz max input frequency • Selectable high impedance buffered input • Input current is 8µA typ at (unbuffered mode, VIN = 5.4V, REFIN = 5.25V) • Operating temperature range is 0°C to +85°C • Packaging style is 8-lead MSOP
