Chapter 1 EVM Overview This chapter provides an overview of the TLC4541/5EVM, TLC3541/5EVM, TLC2551/2/5EVM and TLV2541/2/5EVM. Topic Page Introduction ..........Features . -
Page 10: Introduction
Introduction 1.1 Introduction The series of TLC4541/5, TLC3541/5, TLC2551/2/5 and TLV2541/2/5 are high-performance low-power, miniature, CMOS, serial analog to digital converters (ADCs). The low power performance of these ADCs is further enhanced by an auto-power-down mode incorporated in each series. Three series of the devices run at a maximum sample rate of 200 Ksps and have their own internal conversion clock. -

Page 12: Analog Interface
Analog Interface 1.4 Analog Interface The EVM board is designed for easy interfacing to analog sources such as signal generators and sensors. The buffer amplifier U1 is in a follower configuration, non-inverting gain of one. Output of this buffer drives the AIN(+) pin of the DUT through a 33-W resistor (R4). -
Page 13: Power Supplies
Power Supplies 1.6 Power Supplies The EVM requires three power supplies. 1) A dual-tracking ±12-V supply for the dual-supply op amps U1 and U3. The voltage reference (REF02) is supplied by the +12-V supply. Jumpers W6 and W7 are default settings for this voltage condition. 2) A single +5-V supply is used for the ADC (DUT) and the digital interface. -
