PRINCIPLES OF OPERATION
manufacturer’s test register - address 0x15
This register should only be used by Texas Instruments for testing. Reading or writing to this register during
normal use leads to erroneous events or measurements.
analog output - address 0x19
This register latches an 8-bit value into an R-2R D/A to provide a range of 0 V–2.5 V, accuracy can be ±5% or
more.
company ID - address 0x3E
This location contains the company identification number for TI – 0x49. This register is read only.
stepping - address 0x3F
This location contains the stepping number of the part in the lower four bits of the register [3:0]. The upper four
bits reflect the THMC50 version number [7:4]. The first version is 1100. The next version of the THMC50 would
be 1101, etc. For example, if the stepping were A0 and this part is a THMC50-1, then this register would read
1100 0000. This register is read only.
