AD7450A/AD7440
PIN CONFIGURATION 8-LEAD MSOP
PIN FUNCTION DESCRIPTION
Pin Mnemonic Function
V
REF
Reference Input for the AD7450A/AD7440. An external reference must be applied to this input. For a
5 V powersupply, the reference is 2.5 V (±1%) and for a 3 V power supply, the reference is 2V (±1%)
for specified performance. This pin should be decoupled to GND with a capacitor of at least 0.1μF.
See the ‘Reference Section’ for more details.
Positive Terminal for Differential Analog Input.
Negative Terminal for Differential Analog Input.
Analog Ground. Ground reference point for all circuitry on the AD7450A/AD7440. All analog input
signals and any external reference signal should be referred to this GND voltage.
Chip Select. Active low logic input. This input provides the dual function of initiating a conversion on
the AD7450A/AD7440 and framing the serial data transfer.
Serial Data. Logic Output. The conversion result from the AD7450A/AD7440 is provided on this out-
put as a serial data stream. The bits are clocked out on the falling edge of the SCLK input. The data
stream of the AD7450A consists of four leading zeros followed by the 12 bits of conversion data which
are provided MSB first; the data stream of the AD7440 consists of four leading zeros, followed by the
10-bits of conversion data, followed by two trailing zeros. In both cases, the output coding is two’s
complement.
Serial Clock. Logic input. SCLK provides the serial clock for accessing data from the part. This clock
input is also used as the clock source for the conversion process.
Power Supply Input. V
DD
is 3 V (+20%/-10%) or 5 V (±5%). This supply should be decoupled to
GND with a 0.1μF Capacitor and a 10μF Tantalum Capacitor in parallel.
