Overview

The ADS1015LIYCJR is a 12-bit, 3.3-kSPS precision analog-to-digital converter designed for high-density, low-power applications. This delta-sigma ADC features an internal low-drift voltage reference, an oscillator, and a programmable gain amplifier (PGA) to simplify the measurement of small signals. The device operates from a 2V to 3.6V supply and includes an I2C interface with four pin-selectable addresses.

Why Choose This Part

The ADS1015LIYCJR offers single-cycle settling and a high sampling rate of 3.3-kSPS, making it faster than many comparable delta-sigma ADCs. Its integrated digital comparator with an ALERT pin allows for autonomous system monitoring without constant MCU polling, while the DSBGA package minimizes board footprint.

Applications

Portable Instrumentation
Utilizes the small DSBGA package and low 150uA operating current for handheld measurement tools.
Battery Voltage Monitoring
Monitors multi-cell configurations or individual lithium-ion cells with high precision and low power-down current.
Temperature Sensing
Interfaces directly with thermistors or RTDs using the integrated PGA for signal conditioning.
Process Control
Provides reliable 4-channel single-ended or 2-channel differential measurements in space-constrained industrial modules.

Getting Started

To evaluate this ADC, designers often use the ADS1015EVM evaluation module or compatible I2C breakout boards. Hardware integration requires only a few decoupling capacitors and pull-up resistors for the I2C bus; the internal oscillator and reference eliminate the need for external timing or voltage standards.
