LINEAR TECHNOLOGY  LTC2338IMS-18#PBF  模数转换器, 18 bit, 1 MSPS, 单, 4.75 V, 5.25 V, MSOP

The is a low noise, high speed successive approximation register Analog-to-digital Converter ADC with fully differential inputs. Operating from a single 5V supply, the ADC has a ±10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The ADC achieves ±4LSB INL maximum, no missing codes at 18-bit with 100dB SNR. The ADC has an onboard single-shot capable reference buffer and low drift 2.048V temperature compensated reference. The fast 1Msps throughput with no cycle latency makes the ADC ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The ADC dissipates only 50mW and automatically naps between conversions, leading to reduced power dissipation that scales with the sampling rate. A sleep mode is also provided to reduce the power consumption of the ADC to 300µW for further power savings during inactive periods.
