PI FU CTIO S

SENSE (Pin 1): Reference Sense Pin. GND selects a VREF

of 0.7V. VDD selects 1.125V. When VSENSE is between 0.7V

and 1.125V, VSENSE is used as VREF. The ADC input range

is

±VREF/PGA gain.

VCM (Pin 2): 2.0V Output and Input Common Mode Bias.

Bypass to ground with 4.7

µF ceramic chip capacitor.

GND (Pins 3, 6, 9, 12, 13, 16, 19, 21, 36, 37): ADC Power

Ground.

AIN+ (Pin 4): Positive Differential Analog Input.

AIN– (Pin 5): Negative Differential Analog Input.

VDD (Pins 7, 8, 17, 18, 20): 5V Supply. Bypass to AGND

with 1

µF ceramic chip capacitors at Pin 8 and Pin 18.

REFLB (Pin 10): ADC Low Reference. Bypass to Pin 11

with 0.1

µF ceramic chip capacitor. Do not connect to

Pin 14.

REFHA (Pin 11): ADC High Reference. Bypass to Pin 10 with

0.1

µFceramicchipcapacitor,toPin14witha4.7µFceramic

capacitor and to ground with 1

µF ceramic capacitor.

REFLA (Pin 14): ADC Low Reference. Bypass to Pin 15 with

0.1

µF ceramic chip capacitor, to Pin 11 with a 4.7µF ce-

ramic capacitor and to ground with 1

µF ceramic capacitor.

REFHB (Pin 15): ADC High Reference. Bypass to Pin 14

with 0.1

µF ceramic chip capacitor. Do not connect to

Pin 11.

MSBINV (Pin 22): MSB Inversion Control. Low inverts the

MSB, 2’s complement output format. High does not invert

the MSB, offset binary output format.

ENC (Pin 23): Encode Input. The input sample starts on the

positive edge.

ENC (Pin 24): Encode Complement Input. Conversion

starts on the negative edge. Bypass to ground with 0.1

µF

ceramic for single-ended ENCODE signal.

PGA (Pin 25): Programmable Gain Amplifier Control. Low

selects an effective front-end gain of 1. High selects an

effective gain of 1 2/3. The ADC input range is

±VREF/PGA

gain.

CLKOUT (Pin 26): Data Valid Output. Latch data on the

rising edge of CLKOUT.

OGND (Pins 27, 38, 47): Output Driver Ground.

D0-D3 (Pins 28 to 31): Digital Outputs.

OVDD (Pins 32, 43): Positive Supply for the Output Driv-

ers. Bypass to ground with 0.1

µF ceramic chip capacitor.

D4-D6 (Pins 33 to 35): Digital Outputs.

D7-D10 (Pins 39 to 42): Digital Outputs.

D11-D13 (Pins 44 to 46): Digital Outputs.

OF (Pin 48): Over/Under Flow Output. High when an over

or under flow has occurred.
