Présentation

Description

The ADS7953QDBTRQ1 is a 12-bit, 4-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments, designed for automotive applications. It features a serial peripheral interface (SPI) for communication and operates at a 1-MSPS sampling rate.
Key features include:
- 4 single-ended or 2 differential inputs
- Low power consumption (1.5 mW at 1 MSPS)
- Wide supply range (2.7V to 5.5V)
- AEC-Q100 qualified for automotive environments
The device integrates a programmable reference (internal/external) and offers auto-scan mode for simplified multi-channel sampling. Its small SOT-23-16 package makes it suitable for space-constrained designs.
Ideal for battery monitoring, sensor interfaces, and motor control in automotive systems.
