As an example, use VDD = 1.2V and 12-bit mode with 2MHz SPI clock (fSCLK = 2MHz). The equivalent TSC
throughput is at least seven times faster than the effective throughput across the bus (9.26k x 7 = 64.82kSPS).
The supply current to the TSC for this rate and configuration is 240.08
A. To achieve an equivalent sample
throughput of 8.2kSPS using the device without preprocessing, the TSC2008 consumes only (8.2/64.82) ×
240.08
A = 30.37A.
