Description

Sampling Clock Input

(Input):LVDS The differential clock signal must be a.c. coupled to

10

CLK+

these pins. The input signal is sampled on both the rising and

11

CLK-

falling edge of CLK. See Acquiring the Input for a description of

acquiring the input and THE SAMPLE CLOCK INPUT for an

overview of the clock inputs.

Signal Input

(Input):Analog The differential full-scale input range is 600 mVP-P

18

VIN+

when the FSR pin is low, or 820 mVP-P when the FSR pin is high.

19

VIN−

In the Extended Control Mode, FSR is determined by the Full-Scale

Voltage Adjust register (address 3h, bits 15:7).

Sample Clock Reset

(Input):LVDS A positive differerntial pulse on these pins is used to

reset and synchronize the DCLK outs of multiple converters. See

22

DCLK_RST+

MULTIPLE ADC SYNCHRONIZATION for detailed description.

23

DCLK_RST-

When bit 14 in the Configuration Register (address 1h) is set to 1b,

these differential DCLK_RST pins are selected. See also pin 15

description.

Common Mode Voltage

(Output):Analog - The voltage output at this pin is required to be

the common mode input voltage at VIN+ and VIN− when d.c.

VCMO

coupling is used. This pin should be grounded when a.c. coupling

is used at the analog input. This pin is capable of sourcing or

sinking 100

μA and can drive a load up to 80 pF. See THE

ANALOG INPUT.

Bandgap Output Voltage

31

VBG

(Output):Analog - Capable of 100

μA source/sink and can drive a

load up to 80 pF.
