3 TLA2024EVM-PDK Overview

Various onboard components are used to interface the analog input, digital interface, and provide power to the
TLA2024 device. The

functional block diagram

shows a TLA2024EVM-PDK board overview.

3.1 TLA2024EVM-to-PAMBoard Interface

The TLA2024 supports the digital I

C and functional modes as detailed in the

TLA2024 Ultra-Small, 12-Bit

Analog-to-Digital Data Sheet

. The PAMBoard operates at a 3.3-V logic level and the digital I/O lines of the ADC

are level shifted to match the operating voltage of the TLA2024.

Digital interface connections to the PAMBoard include power and I

C for communication. The digital connections

are highlighted in the silkscreen as shown in

Figure 3-1

. Details regarding the connections are shown in
