0 = Not Used
1 = Software Reset. All Mode Control Registers are Reset to 00h. The ADC is Momentarily Placed in SLEEP Mode.
This Bit is Automatically Set Back to Zero at the End of the SPI Write Command.
The Reset Register is Write Only.

then SDO can be left floating and no pull-up resistor is
needed.Table4showsamapofthemodecontrolregisters.
Software Reset
If serial programming is used, the mode control registers
shouldbeprogrammedassoonaspossibleafterthepower
supplies turn on and are stable. The first serial command
must be a software reset which will reset all register data
bits to logic 0. To perform a software reset, bit D7 in the
reset register is written with a logic 1. After the reset SPI
write command is complete, bit D7 is automatically set
back to zero.
GROUNDING AND BYPASSING
The LTC2175-14/LTC2174-14/LTC2173-14 requires a
printed circuit board with a clean unbroken ground plane.
A multilayer board with an internal ground plane in the
first layer beneath the ADC is recommended. Layout for
the printed circuit board should ensure that digital and
analog signal lines are separated as much as possible. In
particular, care should be taken not to run any digital track
alongside an analog signal track or underneath the ADC.
High quality ceramic bypass capacitors should be used
at the VDD, OVDD, VCM, VREF, REFH and REFL pins. By-
pass capacitors must be located as close to the pins as
possible. Of particular importance is the 0.1F capacitor
between REFH and REFL. This capacitor should be on the
same side of the circuit board as the A/D, and as close to
the device as possible (1.5mm or less). Size 0402 ceramic
capacitors are recommended. The larger 2.2F capacitor
between REFH and REFL can be somewhat further away.
Thetracesconnectingthepinsandbypasscapacitorsmust
be kept short and should be made as wide as possible.
The analog inputs, encode signals, and digital outputs
should not be routed next to each other. Ground fill and
grounded vias should be used as barriers to isolate these
signals from each other.

board. For good electrical and thermal performance, the
Exposed Pad must be soldered to a large grounded pad
on the PC board. This pad should be connected to the
internal ground planes by an array of vias.
