描述The ADS8342 is a 4-channel, 16-bit analog-to-digital converter (ADC). It contains a 16-bit succesive approximation register (SAR), a capacitor-based ADC with an inherent sample-and-hold circuit, an interface for microprocessor use, and parallel 3-state output drivers. The ADS8342 is specified at a 250kHz sampling rate while dissipating only 200mW of power using a ±5V power supply. The ADS8342 is available in a TQFP-48 package and is ensured over the –40°C to +85°C temperature range.特性True Bipolar Input Input Signal Range: ±2.5V 4-Channel Input Multiplexer Up to 250kSPS Sampling Rate Selectable 8-Bit or 16-Bit Parallel Interface 16-Bit Ensured No Missing Codes Offset: 1mV max Low Power: 200mW TQFP-48 Package Operating Temperature Range: –40°C to +85°C APPLICATIONS Data Acquisition Test and Measurement Industrial Process Control Medical Instruments Laboratory Equipment
