ADS7886SDCKR

ADS7886SDCKR Description

The ADS7886SDCKR from Texas Instruments is a high-performance, 12-bit SAR (Successive Approximation Register) ADC designed for precision analog-to-digital conversion in space-constrained applications. Packaged in a compact SC70-6 form factor, this single-channel ADC delivers 1 MSPS sampling rates with low power consumption, making it ideal for portable and battery-operated systems. It operates across a wide analog/digital supply range (2.35V to 5.25V), ensuring compatibility with various logic levels and power sources. The device features a single-ended input and utilizes an internal reference derived from the supply voltage, simplifying design integration. Its SPI-compatible serial interface enables seamless communication with microcontrollers and DSPs.

ADS7886SDCKR Features

• 12-bit resolution with 1 MSPS throughput for high-speed data acquisition.
• Ultra-low power consumption (part of the microPOWER™ series), ideal for energy-sensitive designs.
• Single-supply operation (2.35V–5.25V) for analog and digital domains, reducing external components.
• Integrated reference (supply-referenced) eliminates the need for an external reference circuit.
• SPI interface ensures easy interfacing with host processors.
• SC70-6 package (1.8mm × 2.0mm) suits space-constrained PCBs.
• RoHS3 compliant and REACH unaffected, meeting environmental standards.
• MSL 2 (1 year) moisture sensitivity ensures reliability in humid conditions.

ADS7886SDCKR Applications

The ADS7886SDCKR excels in applications demanding high-speed, low-power, and compact ADCs, such as:
