PIN DESCRIPTION
TC3400
Pin No.
Name
Description
1IN
+
Analog Input. This is the positive terminal of a true differential input
consisting of IN
+ and IN. VIN(n) = (IN+ – IN).(See Electrical Characteristics.)
2IN
Analog Input. This is the negative terminal of a true differential input
consisting of IN
+ and IN. VIN = (IN+ – IN) INcan swing to,
but not below, ground. (See
Electrical Characteristics.)
3
REFIN
Analog Input. The converter’s reference voltage is the differential
between this pin and ground times two. It may be connected to
REFOUT as shown on page 1 or scaled using a resistor divider. Any user supplied
reference voltage less than 1.25V may be used in place of VREFOUT.
4
GND
Ground Terminal.
5
REFOUT
Analog Output. The internal reference connects to this pin. It may be
scaled externally, if desired, and tied to the REFIN input to provide the
converter’s reference voltage. Care must be taken in connecting
external circuitry to this pin. (See
Electrical Characteristics.)
6
SDAT
Digital Output (push-pull). This is the MicroPort serial data output. SDAT is driven low
while the TC3400 is converting data, effectively providing a “busy” signal. After the
conversion is complete, every high- to-low transition on the SCLK pin puts a bit from
the resulting data word on the SDAT pin (from MSB to LSB).
7
SCLK
Digital Input. This is the MicroPort serial clock input. After the conversion starts, each
additional falling edge (up to six) detected on SCLK for t4 seconds reduces the A/D
resolution by one bit. When the conversion is complete, the data word can be shifted
out on the SDAT pin by clocking the SCLK pin.
8VDD
Power Supply Input. (See
Electrical Characteristics.)
