Frequently Asked Questions
What is the resolution and channel count of the ADS1278MPAPTEP?
The ADS1278MPAPTEP features 8 simultaneous-sampling input channels with 24-bit delta-sigma ADC resolution. All 8 channels sample at the same instant, ensuring phase-coherent data acquisition across channels — critical for applications like vibration analysis or power monitoring.
What data rates does the ADS1278MPAPTEP support?
The ADS1278MPAPTEP supports selectable data rates depending on the operating mode: up to 144kSPS in high-speed mode, with lower rates available in high-resolution, low-power, and low-speed modes. This flexibility allows designers to balance throughput, resolution, and power consumption for their specific application.
What are the typical applications for the ADS1278MPAPTEP?
Typical applications include industrial data acquisition, seismic and sonar signal processing, medical instrumentation, vibration monitoring, and power quality analysis. The simultaneous 8-channel sampling and 24-bit resolution make it especially valuable where multi-channel phase accuracy and dynamic range are both required.
What interface does the ADS1278MPAPTEP use and can multiple devices be chained?
The ADS1278MPAPTEP uses a synchronous SPI-compatible serial interface for data output and configuration. It supports daisy-chain connectivity, allowing multiple ADS1278 devices to share a single SPI bus and scale easily to 16, 24, or more simultaneous channels in large acquisition systems.
What is the operating temperature range and what does the 'PTEP' suffix indicate?
The ADS1278MPAPTEP is rated for an extended industrial/military temperature range of -55°C to +125°C. The 'PTEP' suffix denotes an enhanced-plastic space-grade or high-reliability screening level by Texas Instruments, making it suitable for aerospace, defense, and other high-reliability system designs.
