AD7674ACPZ
ANALOG DEVICES AD7674ACPZ 模数转换器, 18 bit, 800 kSPS, 单, 4.75 V, 5.25 V, LFCSP
Product Details
The AD7674 is an 18-bit, 800 kSPS, charge redistribution, successive approximation register SAR fully differential analog-to-digital converter ADC that operates on a single 5 V power supply. The device contains a high speed, 18-bit sampling ADC, an internal conversion clock, an internal reference buffer, error correction circuits, and both serial and parallel system interface ports.
The device is available in a 48-lead LQFP or a 48-lead LFCSP with operation specified from −40°C to +85°C.
Product Highlights
1. High Resolution, Fast Throughput. The AD7674 is an 800 kSPS, charge redistribution, 18-bit, SAR ADC no latency.
2. Excellent Accuracy. The AD7674 has a maximum integral nonlinearity of 2.5 LSB with no missing 18-bit codes.
3. Serial or Parallel Interface. Versatile parallel 18-, 16- or 8-bit bus or 3-wire serial interface arrangement compatible with both 3 V and 5 V logic.
