The AD7623 is a 16-bit, 1.33 MSPS, charge redistribution SAR, fully differential analog-to-digital converter (ADC) that operates from a single 2.5 V power supply. It contains a high speed 16-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and both serial and parallel system interface ports. Power consumption is automatically scaled with throughput, making it ideal for battery-powered applications. It is available in 48-lead, low profile quad flat package (LQFP) and a lead frame chip-scale (LFCSP_VQ) package. Operation is specified from −40°C to +85°C.
PRODUCT HIGHLIGHTS
- Fast Throughput: The AD7623 is a 1.33 MSPS, charge redistribution, 16-bit SAR ADC.
- Superior Linearity: The AD7623 has no missing 16-bit code.
- Internal Reference: The AD7623 has a 2.048 V internal reference with a typical drift of ±7 ppm/°C.
- Single-Supply Operation: The AD7623 operates from a 2.5 V single supply and typically dissipates 45 mW. Its power dissipation decreases with the throughput.
- Serial or Parallel Interface: Versatile parallel (16- or 8-bit bus) or 2-wire serial interface arrangement compatible with 2.5 V, 3.3 V, or 5 V logic.
