Texas Instruments ADS1015EVM

Overview

ADS1015EVM from Texas Instruments is a stand-alone evaluation module for the ADS1015, a 12-bit, 4-channel delta-sigma analog-to-digital converter with I²C interface, onboard dual-device configuration, and support for ±10V analog input via modular EVM system power rails. It enables full functional and performance validation of the ADS1015 in sensor signal conditioning, industrial monitoring, and data acquisition prototyping.

For engineers reviewing the ADS1015EVM datasheet, ADS1015EVM pinout, ADS1015EVM application, or ADS1015EVM equivalent, this page delivers verified technical context, key specifications, supply readiness, manufacturer background, and targeted FAQs - all grounded in TI's official SBAU157B User's Guide and EVM documentation.

Technical Context

The ADS1015EVM implements a dual-ADS1015 architecture (U1 and U2), each supporting programmable gain amplifier (PGA) gains of 0.67× to 16×, eight selectable analog input multiplexing configurations (e.g., AIN0:GND, AIN0:AIN1), and comparator-based alert triggering with latching/non-latching modes. It interfaces exclusively via 3.3V I²C (SDA/SCL) and exposes all analog inputs through a 10-pin Samtec header (J1).

Power is configurable via jumper JMP1 and switch S1 to accept +3.3VD, +5VD, or external ±10V analog supplies (via J2), with separate AGND/DGND routing and on-board current measurement points for VDD1/VDD2. The board is fully compatible with TI's Modular EVM System and requires an external host controller (e.g., MMB3 motherboard or custom microcontroller) for digital control and data readout.

FAQ

What is the ADS1015EVM used for?

The ADS1015EVM is a dedicated evaluation module for the ADS1015 12-bit delta-sigma ADC. It allows engineers to validate device functionality-including programmable gain, analog input multiplexing, I²C communication, and comparator operation-without designing custom hardware. ADS1015EVM supports rapid prototyping of sensor interfaces, battery-powered data loggers, and industrial monitoring systems by providing immediate access to all critical pins and configurable power options.

Does the ADS1015EVM include software or require a host controller?

The ADS1015EVM itself contains no microprocessor and cannot run software independently. It requires an external host controller such as TI's MMB3 motherboard (when used as part of the ADS1015EVM-PDK kit) or a custom microcontroller with I²C capability. Evaluation is performed using TI's ADCPro software, which communicates with the ADS1015EVM via the host interface to configure registers, acquire data, and perform FFT/histogram analysis.

Can the ADS1015EVM operate with both ADS1015 and ADS1115 devices?

Yes - the ADS1015EVM PCB is mechanically and electrically identical to the ADS1115EVM and supports both the 12-bit ADS1015 and 16-bit ADS1115. The same board layout, jumper configurations, pinouts, and software interface apply. However, data rate options differ: ADS1015EVM supports 128–3300 SPS (with effective sampling capped at 920 SPS when using MMB3), while ADS1115EVM supports 8–860 SPS in continuous mode.

How is power supplied to the ADS1015EVM?

ADS1015EVM accepts power via three options: +3.3VD, +5VD, or external analog supply (±10V) through connector J2. Selection is controlled by switch S1 and configured using JMP1 jumpers for VDD1, VDD2, and ground bonding. When used with the MMB3 in the ADS1015EVM-PDK kit, power is delivered entirely over USB, with the MMB3 generating regulated 3.3V/5V rails and ±10V analog supplies for the daughtercard.

What are the key interface connectors on the ADS1015EVM?

The ADS1015EVM features three primary connectors: J1 (10-pin Samtec header) for analog inputs (AIN0–AIN3 ×2) and AGND; J3 (10-pin Samtec header) for digital signals including I²C (SDA/SCL), ALERT/RDY outputs (GPIO0/GPIO1), and DGND; and J2 (10-pin header) for power input with configurable +VA, +5VD, +3.3VD, AGND, and DGND pins. All headers use Samtec SSW/TSM series mating connectors for reliable modular integration.
