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 ADIS16080 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. Represents the angular rate signal.

6

FILT

I

External Capacitor Connection to Control Bandwidth.

7

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 (see Table 5).

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 (see Table 5).

10

COM

S

Common. Reference point for all circuitry in the ADIS16080.

11

O

Precision 2.5 V Reference.

12

ST2

I

Self-Test Input 2.

13

ST1

I

Self-Test Input 1.

14

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.
