Pin No. Mnemonic Type1 Description
1
DIN
I
Data In. Data to be written to the control register is provided on this input and is clocked in on the
falling edge of the SCLK.
2
SCLK
I
Serial Clock. SCLK provides the serial clock for accessing data from the part and writing serial data
to the control registers. Also used as a clock source for the ADIS16100 conversion process.
3
DOUT
O
Data Out. The data on this pin represents data being read from the control registers and is clocked
on the falling edge of the SCLK.
4
NC
No Connect.
5
RATE
O
Buffered analog output representing the angular rate signal.
6
FILT
I
External capacitor connection to control bandwidth.
7
VDRIVE
S
Power to SPI. The voltage supplied to this pin determines the voltage at which the serial interface
operates.
8
AIN1
I
External Analog Input Channel 1. Single-ended analog input multiplexed into the on-chip track-
and-hold according to the setting of the ADD0 and ADD1 address bits.
9
AIN2
I
External Analog Input Channel 2. Single-ended analog input multiplexed into the on-chip track-
and-hold according to the setting of the ADD0 and ADD1 address bits.
10
COM
S
Common. Reference point for all circuitry in the ADIS16100.
11
VREF
O
Precision 2.5 V Reference.
12
ST2
I
Self Test Input 2.
13
ST1
I
Self Test Input 1.
14
VCC
S
Analog Power.
15
NC
No Connect.
16
CS
I
Chip Select. Active low. This input frames the serial data transfer and initiates the conversion
process.
1 I = Input; O = Output; S = Power supply.
