Product details
Overview
XE8000EV120 from Semtech is an evaluation board designed to demonstrate and validate the SX8722 high-resolution analog front-end IC for pressure sensor interfacing, featuring ZoomingADC™ architecture with 16-bit resolution, 307.2 kHz sampling rate, and programmable PGA gain up to 825× for precision atmospheric pressure measurement in barometric sensing applications.
For engineers reviewing the XE8000EV120 datasheet, pinout, applications, or equivalent options, this page provides verified hardware configuration details, ZoomingADC™ setup guidance, differential sensor interface schematics, GUI-based register programming workflow, and real-world noise performance metrics derived from the official Semtech Application Note AN-XE8000EV120.
Technical Context
The XE8000EV120 implements a complete signal chain for MPX2202AP-type absolute pressure sensors, using the SX8722 AFE's three-stage PGA (PGA1=10×, PGA2=10×, PGA3=8.25×), VREF-referenced offset cancellation, and configurable moving-average digital filtering. It supports differential AC0/AC1 input with sign inversion capability to accommodate inverted sensor output polarity.
Its core function is enabling high-fidelity digitization of sub-10mV sensor spans (e.g., 4.5–8.5 mV over 88.7–107.8 kPa) via dynamic gain scaling, achieving 62.9 nV LSB input voltage equivalence and 8 cm altitude resolution - validated through comparative zoomed vs. non-zoomed ADC output analysis showing 320% signal span improvement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Type | Evaluation platform for SX8722 analog front-end IC, not a standalone IC or sensor. |
| Target Sensor | Freescale MPX2202AP 0–200 kPa absolute pressure sensor with 3.3 V supply and 13.04 mV full-scale output. |
| AFE Core | SX8722 with ZoomingADC™ architecture, 16-bit resolution, 307.2 kHz sampling frequency, and oversampling rate of 1024. |
| PGA Configuration | Three-stage programmable gain amplifier: PGA1 = 10×, PGA2 = 10×, PGA3 = 8.25×, total gain = 825× for optimized atmospheric window (88.7–107.8 kPa). |
| Input Interface | Differential analog input via AC0/AC1 pins; supports sign inversion and VREF-based offset cancellation (−1.58 × VREF applied at PGA3). |
| Filtering | Configurable moving-average digital filter; default setting uses 10-sample averaging, extended to 70 samples for zoomed-mode noise reduction. |
| LSB Input Voltage | 62.9 nV - enables detection of ~0.096 kPa pressure change or ~8 cm altitude shift under typical sensor transfer function. |

FAQ
What is the primary function of the XE8000EV120?
The XE8000EV120 is an evaluation board-not an IC or sensor-that demonstrates the SX8722 analog front-end IC's ZoomingADC™ capability for high-resolution pressure measurement. It provides hardware connectivity, USB interface, and GUI software to configure PGA gains, offset cancellation, and digital filtering for sensors like the MPX2202AP. The XE8000EV120 enables rapid validation of full signal-chain performance before custom PCB design.
Which sensor is explicitly validated with the XE8000EV120 in official documentation?
The Freescale MPX2202AP 0–200 kPa absolute pressure sensor is the only sensor explicitly validated with the XE8000EV120 in Semtech's Application Note AN-XE8000EV120. It operates at 3.3 V supply, draws 1.96 mA, and delivers a 13.04 mV full-scale output. All gain calculations, offset settings, and zoom window definitions in the XE8000EV120 documentation are derived from this specific sensor's transfer function and electrical characteristics.
Does the XE8000EV120 include the SX8722 IC onboard?
Yes, the XE8000EV120 evaluation board integrates the SX8722 analog front-end IC as its core signal-processing element. The board routes sensor inputs to the SX8722's AC0/AC1 differential inputs and AR0/AR1 reference inputs, exposes all necessary control signals, and connects the SX8722's serial interface to a USB-to-serial bridge for GUI communication. The XE8000EV120 cannot function without the onboard SX8722 IC.
How does the "ZoomingADC™" feature improve measurement accuracy on the XE8000EV120?
ZoomingADC™ dynamically scales gain and offset to focus the ADC's full 16-bit range on a narrow input voltage window-e.g., 4.5–8.5 mV for atmospheric pressure changes-instead of the full sensor span (0–13.04 mV). As documented in the XE8000EV120 Application Note, this increases usable signal span by 320%, reduces effective LSB size to 62.9 nV, and improves altitude resolution to ~8 cm, directly validated using the MPX2202AP sensor and SX8722 registers.
Is the XE8000EV120 compatible with other Semtech AFEs besides the SX8722?
No-the XE8000EV120 is purpose-built for the SX8722 and references no other Semtech AFE. Its schematic, pin assignments, GUI software, and all configuration examples (including PGA gain tables, filter settings, and register maps) are exclusively tied to the SX8722. The board lacks hardware provisions or firmware support for alternative AFEs such as SX8720, SX8721, or SX8723, and Semtech's documentation makes no cross-compatibility claims for the XE8000EV120.
