1. Introduction
The Texas Instruments LM75AEB evaluation board (EB) helps designers evaluate the operation and
performance of the LM75A, an industry-standard digital temperature sensor with an integrated Sigma-Delta
analog-to-digital converter and I
accuracy of ±2°C from -25°C to 100°C and ±3°C over -55°C to 125°C.
The EVM contains one Digital Temperature Sensor (See Table 1).
