Introduction

1 Introduction
The TLA2024EVM-PDK is a fully-assembled evaluation platform designed to highlight the TLA2024 features and
modes of operation that make this device suitable for low-power applications. The EVM sits on top of an
accompanying Precision ADC Motherboard (PAMBoard) used as a USB-to-PC GUI communication bridge. The
board combination also serves as an example implementation of connecting a microcontroller (MCU) to
communicate with the TLA2024 device through an Inter-Integrated Circut interface (I
The TLA2024 EVM requires an external controller to evaluate the TLA2024 device.
The PAMBoard is controlled by commands received from the TLA2024EVM-PDK GUI, and returns data to the
GUI for display and analysis. If the PAMBoard is not used, the EVM plug-in module format allows for an
alternative external host to communicate with the TLA2024 by connection through the pin headers J1 through
J4. Connections to the header are identified on the
The combined TLA2024EVM and PAMBoard make up the TLA2024EVM-PDK and incorporates the following
features:
• TLA2024, four input-channel ADC with header or screw terminal block input connections
• Voltage selection of 3.3 V or 5 V operation for the TLA2024 with level-shifting to the 3.3-V MCU
• Full-scale ranges from 256 mV to 6.144 V

• I C for communication and configuration
