TSC2111 Buffer Data Registers (Page 3)
The buffer data registers of the TSC2111 hold data results from the SAR ADC conversions in buffer mode. Upon
reset, bit D15 is set to 0, bit D14 is set to 1 and the remaining bits are don’tcare. These registers are read only.
If buffer mode is enabled, then the results of all ADC conversions are placed in the buffer data register. The
data format of the result word (R) of these registers is right-justified which is as follows:

LAYOUT
The following layout suggestions should provide optimum performance from the TSC2111. However, many
portable applications have conflicting requirements concerning power, cost, size, and weight. In general, most
portable devices have fairly clean power and grounds because most of the internal components are very low
power. This situation would mean less bypassing for the converter’s power and less concern regarding
grounding. Still, each situation is unique and the following suggestions should be reviewed carefully.
For optimum performance, care should be taken with the physical layout of the TSC2111 circuitry. The basic
SAR architecture is sensitive to glitches or sudden changes on the power supply, reference, ground
connections, and digital inputs that occur just prior to latching the output of the analog comparator. Therefore,
during any single conversion for an n-bit SAR converter, there are n windows in which large external transient
voltages can easily affect the conversion result. Such glitches might originate from switching power supplies,
nearby digital logic, and high power devices. The degree of error in the digital output depends on the reference
voltage, layout, and the exact timing of the external event. The error can change if the external event changes
in time with respect to the timing of the critical n windows.
