The HI5710A is a low power, 10-bit, CMOS analog-to-digital
converter. The use of a 2-step architecture realizes low
power consumption, 150mW, and a maximum conversion
speed of 20MHz with only a 3 clock cycle data latency. The
HI5710A can be powered down, disabling the chip and the
digital outputs, reducing power to less than 5mW. A built-in,
user controllable, calibration circuit is used to provide low
linearity error, 1 LSB. The low power, high speed and small
package outline make the HI5710A an ideal choice for CCD,
battery, and high channel count applications.
The HI5710A does not require an external sample and hold
but requires an external reference and includes force and
sense reference pins for increased accuracy. The digital out-
puts can be inverted, with the MSB controlled separately,
allowing for various digital output formats. The HI5710A
includes a test mode where the digital outputs can be set to
a fixed state to ease in-circuit testing.
