模数转换器, 14 bit, 1.5 MSPS, 差分, SPI, 单, 4.75 V
The from is an octal, 14bit + sign, 1.5Msps/ch simultaneous sampling ADC in 52 pin QFN package. The LTC2320-14 has an 8VP-P differential input range making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2320-14 ADC achieves ±1LSB INL typical, no missing codes at 14bit and 81dB SNR. It has an onboard low drift 20ppm/°C max 2.048V or 4.096V temperature-compensated reference. It also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 1.5Msps per channel throughput with no latency makes the LTC2320-14 ADC ideally suited for a wide variety of high speed applications. It is used in high speed data acquisition systems, communications, optical networking and multiphase motor control.
