CONFIGURATION REGISTER
RS2, RS1, RS0 = 0, 1, 0; Power-On/Reset = 0x0710
The configuration register is a 16-bit register from which data can be read or to which data can be written. This register is used to con-
figure the ADC for unipolar or bipolar mode, enable or disable the buffer, enable or disable the burnout currents, select the gain, and
select the analog input channel. Table 17 outlines the bit designations for the filter register. CON0 through CON15 indicate the bit
locations; CON denotes that the bits are in the configuration register. CON15 denotes the first bit of the data stream. The number in
parentheses indicates the power-on/reset default status of that bit.

Bias Voltage Generator Enable. The negative terminal of the analog inputs can be biased up to AVDD/2. These
bits are used in conjunction with the boost bit.

CON13
BO
Burnout Current Enable Bit. When this bit is set to 1 by the user, the 100 nA current sources in the signal path
are enabled. When BO = 0, the burnout currents are disabled. The burnout currents can be enabled only
when the buffer or in-amp is active.
CON12
U/B
Unipolar/Bipolar Bit. Set by user to enable unipolar coding; that is, zero differential input results in 0x000000
output, and a full-scale differential input results in 0xFFFFFF output. Cleared by the user to enable bipolar
coding. Negative full-scale differential input results in an output code of 0x000000, zero differential input
results in an output code of 0x800000, and a positive full-scale differential input results in an output code of
0xFFFFFF.
CON11
BOOST
This bit is used in conjunction with the VBIAS1 and VBIAS0 bits. When set, the current consumed by the bias
voltage generator is increased. This reduces its power-up time.
