ADC Single SAR 500ksps 16-bit Serial 24-Pin VQFN EP T/R, ADS8331IRGER, Texas Instruments

The ADS8331 is a low-power, 16-bit, 500k samples-per-second (SPS) analog-to-digital converter (ADC) with a unipolar, 4-to-1 multiplexer (mux) input. The device includes a 16-bit capacitor-based successive approximation register (SAR) ADC with inherent sample and hold. The ADS8332 is based on the same core and includes a unipolar 8-to-1 input mux. Both devices offer a high-speed, wide-voltage serial interface and are capable of daisy-chain operation when multiple converters are used. These converters are available in 24-pin, 4×4 QFN and 24-pin TSSOP packages and are fully specified for operation over the industrial –40°C to +85°C temperature range. 

  • Low-Power, Flexible Supply Range:
    • 2.7V to 5.5V Analog Supply
    • 8.7mW (250kSPS in Auto-Nap Mode,
      VA = 2.7V, VBD = 1.65V)
    • 14.2mW (500kSPS, VA = 2.7V, VBD = 1.65V)
  • Up to 500kSPS Sampling Rate
  • Excellent DC Performance:
    • ±1.2 LSB Typ, ±2 LSB Max INL at 2.7V
    • ±0.6 LSB Typ, –1.0/1.5 LSB Max DNL at 2.7V
    • 16-Bit NMC Over Temperature
  • Excellent AC Performance at 5V, fIN = 1kHz:
    • 91.5dB SNR, 101dB SFDR, –100dB THD
  • Flexible Analog Input Arrangement:
    • On-Chip 4-/8-Channel Mux with Breakout
    • Auto/Manual Channel Select and Trigger
  • Other Hardware Features:
    • On-Chip Conversion Clock (CCLK)
    • Software/Hardware Reset
    • Programmable Status/Polarity EOC/INT
    • Daisy-Chain Mode
    • Global CONVST (Independent of CS)
    • Deep, Nap, and Auto-Nap Powerdown Modes
    • SPI™/DSP Compatible Serial Interface
    • Separate I/O Supply: 1.65V to VA
    • SCLK up to 40MHz (VA = VBD = 5V)
  • 24-Pin 4×4 QFN and 24-Pin TSSOP Packages
