Source Code Provided The MAX197 EV kit requires a single +5V supply and Fully Assembled and Tested includes optional input buffer amplifiers that operate with 15V supplies. User-Selected Microcontroller Module 80C32 or 68HC16 The MAX197 EV kit and EV system evaluate both the MAX197 and the MAX199. To evaluate the MAX199, order a sample of the MAX199 along with the MAX197 Ordering Information EV kit. PART TEMP.
