Analog to Digital Converters

ADS1254WDBQEP Description

The ADS1254WDBQEP from Texas Instruments is a high-precision, 24-bit sigma-delta analog-to-digital converter (ADC) designed for demanding measurement applications. This obsolete but still relevant IC features a single-channel architecture with 4 differential inputs, enabling accurate signal acquisition in noisy environments. Operating with a 5V analog supply and a flexible 1.8V to 3.6V digital supply, it supports SPI interface for seamless integration with microcontrollers and DSPs. The device delivers a 20kSPS sampling rate, making it suitable for medium-speed, high-resolution data acquisition. Packaged in a 20-pin SSOP (Shrink Small Outline Package), it is optimized for surface-mount applications where space and precision are critical.

ADS1254WDBQEP Features

• 24-bit resolution for ultra-high precision measurements.
• Differential input configuration reduces common-mode noise.
• SPI-compatible serial interface ensures easy communication with host systems.
• External reference voltage support for enhanced flexibility.
• Wide digital supply range (1.8V–3.6V) enables compatibility with low-power systems.
• 20kSPS sampling rate balances speed and resolution for industrial applications.
• ROHS3 compliant and REACH unaffected, meeting environmental standards.
• Moisture Sensitivity Level (MSL) 2 ensures reliability in humid conditions.

ADS1254WDBQEP Applications

This ADC is ideal for applications requiring high-resolution signal conversion with moderate speed, such as:

• Industrial process control (e.g., pressure, temperature, and strain measurement).
• Medical instrumentation (e.g., patient monitoring, ECG systems).
• Precision weigh scales and load cells.
• Seismic monitoring and vibration analysis.
• Automotive sensor interfaces (e.g., torque and position sensing).

Conclusion of ADS1254WDBQEP

The ADS1254WDBQEP stands out for its 24-bit resolution, differential inputs, and robust SPI interface, making it a reliable choice for precision measurement systems. While marked as obsolete, its performance characteristics remain valuable for legacy designs or applications where high accuracy and noise immunity are paramount. Engineers seeking a high-resolution, medium-speed ADC with flexible power requirements will find this IC well-suited for industrial, medical, and automotive sensing applications.
