The ADS7851IRTER from Texas Instruments is a 14-bit, dual-channel analog-to-digital converter with a sampling rate of 1.5 MSPS. It features a sample-and-hold (S/H-ADC) architecture for accurate signal capture. The SPI interface provides high-speed serial communication with microcontrollers and DSPs. This ADC operates over a wide temperature range of -40°C to 125°C, making it suitable for automotive and industrial applications. It includes an internal reference, simplifying design and reducing external component count. The 16-WFQFN exposed pad package offers excellent thermal performance and a compact footprint for space-constrained designs.
- Fast Sampling: 1.5 MSPS enables real-time capture of high-frequency signals.
- Dual Channels: Simultaneous sampling of two signals reduces system complexity.
- Internal Reference: Eliminates the need for an external reference IC, saving cost and board space.
- Wide Temperature Range: -40°C to 125°C ensures reliable operation in extreme conditions.
- Compact Package: 16-WFQFN package is ideal for portable and dense designs.
High-Speed Motor Control
The 1.5 MSPS sampling rate and 14-bit resolution allow for precise and fast current/voltage sensing in motor control loops, enabling smoother and more efficient operation of industrial drives.
Power Inverter Monitoring
In solar inverters and UPS systems, the dual channels can simultaneously monitor DC bus voltage and current, with the high sampling rate capturing fast transients for protection circuits.
Audio Signal Processing
The 14-bit resolution and 1.5 MSPS rate are suitable for high-quality audio digitization in professional audio equipment, providing good dynamic range for music recording.
Automotive Sensor Interfaces
With a -40°C to 125°C range, this ADC is ideal for automotive applications like engine control units, where two analog sensors (e.g., throttle position and manifold pressure) need fast, accurate conversion.
Portable Instrumentation
The compact WFQFN package and low power consumption make it suitable for battery-powered oscilloscopes and logic analyzers that require dual-channel high-speed acquisition.
Industrial Data Loggers
For high-speed data logging in test benches, the dual channels allow simultaneous recording of two signals, while the SPI interface simplifies connection to SD card loggers.
