SA5775A Pin Descriptions for the N Package (Dual In-Line)
Pin #
Name
Function
1.
SIN–
Negative output connection to the SIN coil of the gauge.
2.
SIN+
Positive output connection to the SIN coil of the gauge.
3.
AGND
Ground for VIGN supply. Pins 3, 13 and 14 connected on the circuit board.
4.
VIGN
Analog supply. Nominally 14.0 V.
5.
DATAOUT Serial data output. Output of the internal shift register. When a new data word is shifted in, the old word is shifted out the
DATAOUT pin.
6.
DATAIN
Serial data input. A new data word is serially shifted into the part on the rising edge of SCLK. The data is shifted in MSB first.
7.
VCC
5 V logic supply. The internal latches and registers are set to zero on the rising edge of this signal.
8.
OE
Output drivers are turned off when this input is low. Current draw is minimized.
9.
SCLK
Serial clock input. Data is loaded into the part on the rising edge of SCLK.
10.
CS
Active high chip select input. When CS is high, the part is enabled to receive a new serial input word. The high-to-low tran-
sition of CS loads the new 10-bit word into the DAC registers and updates the output.
11.
ST
Status output from this IC to indicate that the outputs have been disabled. The outputs may be disabled due to shorted out-
puts, over temperature conditions, power up reset, or output enable control pin .This output is an open drain output .Multiple
status outputs may be wire OR’ed together .This output is low when the outputs are disabled due to a fault condition.
12.
nc
Not connected
13.
DGND
Ground for VCC supply. Connect to Pins 3 and 14.
14.
AGND
Ground for VBB supply. Connect to Pins 3 and 13.
15.
COS–
Negative output connection to the COS coil of the gauge.
16.
COS+
Positive output connection to the COS coil of the gauge.
