ADX3224/6/8 4-, 6-, and 8-Channel, 24-Bit, Simultaneously-Sampling, Delta-Sigma ADC 1. FEATURES 3. DESCRIPTION • Eight differential ADC inputs • Outstanding performance: Dynamic range: 116dB at 500SPS and 113dB at 1kSPS CMRR: 125dB Crosstalk: −120dB THD: −100dB at 50Hz and 60Hz Analog supply range options: 3V to 5V (unipolar) ±2.5V (bipolar, allows DC coupling) The ADX3224/6/8 is a family of multichannel, simultaneous sampling, 24-bit, delta-sigma (ΔΣ), analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator. The ADC wide dynamic range, scalable data rates, and internal fault detect monitors make the ADX3224/6/8 attractive in industrial power monitoring and protection as well as test and measurement applications. True high-impedance inputs enable the ADX3224/6/8 to directly interface with a resistor-divider network or a voltage transformer to measure line voltage, or a current transformer or Rogowski coil to measure line current. With high integration levels and exceptional performance, the ADX3224/6/8 family enables the creation of scalable industrial power systems at significantly reduced size, power, and low overall cost. • • Digital: 1.8V to 3.6V • Two work modes with different data rate: High-Speed:1, 2, 4, 8, 16, 32 and 64kSPS Low-Speed: 500sps, 1, 2, 4, 8, 16, 32kSPS • Programmable gains: 1, 2, 4, 8, 12, 24, 48 • Fault detection and device testing capability • VDAC excitation source • SPI™ data interface and four GPIOs, daisy chain. • Package: TQFP-64, BGA-64 • Operating temperature range: −40°C to 105°C 2. APPLICATIONS • Power protection: circuit breakers, and relay protection • Energy metering: single phase, polyphase, and power quality • Battery test systems • Test and measurement • Simultaneous sampling data acquisition systems © 2023 AnalogySemi Ltd. All Rights Reserved. The ADX3224/6/8 has a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and fault detection. Fault detection can be implemented internal to the device, using the integrated comparators with digital-to-analog converter (DAC) controlled trigger levels. The ADX3224/6/8 can operate at data rates as high as 64kSPS. These complete analog front-end (AFE) solutions are packaged in a TQFP-64 package and BGA-64 are specified over the industrial temperature range of −40°C to 105°C. See Table 1 for the order information. Confidential www.analogysemi.com | Page 1 of 82 PDF
