The document introduces the features and characteristics of ADS1206 and ADS1207 low-cost, high-performance, synchronous voltage-to-frequency converters (VFC), including synchronous operation, external clock setting, maximum input frequency, selectable high-impedance buffered input, 2.5V reference voltage, high-current output driver, 3.3V or 5V power supply, low power consumption, alternate source for AD7740, -40°C to +85°C operating temperature range.
The ADS1206 and ADS1207 are low-cost, high-performance, synchronous voltage-to-frequency converters (VFC) designed for medium-resolution measurements. Both devices operate from a single 3.0V to 3.6V or 4.5V to 5.5V power supply and consume only 1mA. The output signal is synchronous with the input clock, CLKIN, which is TTL- and CMOS-compatible. The onboard clock generator can also accept an external crystal or resonator.
