DESCRIPTION
The
ADS1206
high-performance, synchronous voltage-to-frequency
converters (VFC). Both devices can operate from a single
3.0V to 3.6V or 4.5V to 5.5V power supply, consuming only
1mA. The output signal is synchronous with the input
clock, CLKIN. The clock input is TTL- and CMOS-
compatible and the onboard clock generator can also
accept an external crystal or resonator. The maximum
input clock frequency for the ADS1206 is 1MHz and for the
ADS1207 is 4MHz. The clock divider on the ADS1207
scales the input frequency to 2MHZ, which permits the
core to operate at the higher rate. The high-impedance
input is ideal for direct connection to high-impedance
transducers or high-voltage resistive dividers. Counting
output pulses over a 4ms period results in an effective
12-bit resolution for the ADS1206 using a 1MHz input
clock. For the ADS1207 using a 4MHz input clock, the
same result occurs over a 2ms period. Both devices are
designed for use in medium-resolution measurements.
They are available in an 8-lead VSSOP package.
