Description
1
SCLK
Serial Clock. Schmitt triggered logic input. An external serial clock is applied to this input
to transfer serial data to or from the AD7732.
2
MCLKIN
Master Clock Signal for the ADC. This can be provided in the form of a crystal/resonator
or external clock. A crystal/resonator can be tied across the MCLKIN and MCLKOUT pins.
Alternatively, the MCLKIN pin can be driven with a CMOS compatible clock and
MCLKOUT left unconnected.
3
MCLKOUT
When the master clock for the device is a crystal/resonator, the crystal/resonator is
connected between MCLKIN and MCLKOUT. If an external clock is applied to the
MCLKIN, MCLKOUT provides an inverted clock signal or can be switched off to reduce
the device power consumption. MCLK OUT is capable of driving one CMOS load.
4
CS
Chip Select. Active low Schmitt triggered logic input with an internal pull-up resistor.
With this input hardwired low, the AD7732 can operate in its 3-wire interface mode
using SCLK, DIN, and DOUT. CS can be used to select the device in systems with more
than one device on the serial bus. It can also be used as an 8-bit frame
synchronization signal.
5
RESET
Schmitt Triggered Logic Input. Active low input that resets the control logic, interface
logic, digital filter, analog modulator, and all on-chip registers of the part to power-on
status. Effectively, everything on the part except the clock oscillator is reset when the
RESET pin is exercised.
6
AVDD
Analog Positive Supply Voltage. 5 V to AGND nominal.
7
P0
Digital Input/Output. The pin direction is determined by the P0 DIR bit; the digital
value can be read/written as the P0 bit in the I/O port register. The digital voltage is
referenced to analog supplies. When configured as an input, the pin should be tied
high or low.
