Product Overview
The ADS7864Y/2K is a 12‑bit SAR simultaneous‑sampling ADC from TI. It features 6 fully‑differential inputs in 3 sampling pairs, 500 kSPS per‑channel parallel output, built‑in 2.5V reference. Suitable for 3‑phase motor control, UPS and power monitoring. “/2K” stands for 2000‑piece tape‑and‑reel package.
Core Advantages
Three‑Pair Simultaneous Differential Sampling
Six differential inputs for synchronous multi‑phase measurement with zero phase skew.
500kSPS & 12‑Bit No‑Missing‑Codes
500 kSPS per‑channel rate, reliable for industrial dynamic signal acquisition.
High On‑Chip Integration
Integrated 2.5V reference reduces external components and PCB footprint.
Parallel Interface & Wide IO Compatibility
True parallel interface (not SPI). 2.7V‑5.25V IO, works with 3.3V / 5V MCU, DSP and FPGA.

Frequently Asked Questions
Q1: What does the “/2K” suffix mean for ADS7864Y/2K?
A: “/2K” is 2000‑piece tape‑and‑reel. The /250 suffix is 250‑piece reel. Same chip, only reel quantity differs.
Q2: Difference between ADS7864Y and ADS7864B?
A: ADS7864Y: industrial grade ‑40℃~+85℃. ADS7864B: commercial grade 0℃~+70℃. Pin‑compatible, cannot cross‑grade replace for low‑temp industrial applications.
Q3: Is ADS7864Y/2K SPI interface?
A: No, it uses true parallel interface. Some platforms mislabel as SPI, signal pins include /CS, /RD, /HOLDX, BUSY and 12‑bit data bus.
Q4: Why simultaneous sampling matters for motor control?
A: Captures multi‑phase voltage and current at the same instant, eliminates channel phase skew for accurate motor vector control.
Q5: What are pin‑to‑pin compatible alternatives?
A: ADS7864I shares identical pinout. ADS7865 is higher‑speed version with same package and parallel interface for power acquisition.
Q6: How to get datasheet, CAD files or bulk price?
A: Submit via Quick Inquiry for original datasheet, PCB footprint, real‑time stock and volume quotation.
