PIN DESCRIPTION
TC3402
Pin No.
Name
Description
1,3,5,12
INn
+
Analog Input. This is the positive terminal of a true differential input
consisting of INn
+ and INn–. VIN(n) = (INn+ – INn–).(See Electrical
Characteristics.)
2,4,6,11
INn
–
Analog Input. This is the negative terminal of a true differential input
consisting of INn
+ and INn– . VIN(n) = (INn+ – INn–) INn– can swing to,
but not below, ground. (See
Electrical Characteristics.)
7
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 or the power supply rail may be used in place of REFOUT.
8
GND
Ground Terminal.
9
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.)
10
SDAT
Digital Output (push-pull). This is the MicroPort serial data output.
SDAT is driven low while the TC3402 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).
13
A1
Digital Input. Controls analog multiplexer in conjunction with A0 to select
one of the four Input channels. This address is latched at the falling edge
of the SCLK, which starts an A/D conversion. A1,A0 = 00 = Input 1;
01 = Input 2; 10 = Input 3; 11 = Input 4.
14
A0
Digital Input. Controls analog multiplexer in conjunction with A1 to select
one of four Input channels. This address is latched at the falling edge of
the SCLK, which starts an A/D conversion. A1,A0 = 00 = Input 1;
01 = Input 2; 10 = Input 3; 11 = Input 4.
15
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.
16
VDD
Power Supply Input. (See Electrical Characteristics.)
