描述The ADS7810 is a complete 12-bit sampling analog-to-digital converter (A/D) using state-of-the-art CMOS structures. It contains a complete 12-bit capacitor-based SAR A/D with inherent S/H, reference, clock, interface for microprocessor use, and 3-state output drivers. The ADS7810 is specified at an 800kHz sampling rate, and ensured over the full temperature range. Laser-trimmed scaling resistors provide the industry-standard ±10V input range, while an innovative design allows operation from ±5V supplies. The 28-pin ADS7810 is available in a plastic SOIC fully specified for operation over the industrial –40°C to +70°C range.特性 1.25μs Throughput Time Standard ±10V Input Range 69dB Min SINAD With 250kHz Input ±3 LSB Max INL and ±3 LSB Max DNL Internal Reference Complete With S/H, REF, CLOCK, ETC.
