AD7890SQ-10

AD7890 is an 8-channel 12bit data acquisition system. The part contains an input multiplexer, an on-chip track/hold amplifier, a high speed 12bit ADC, a 2.5V reference and a high speed, serial interface. The multiplexer on the part is independently accessible. This allows the user to insert an antialiasing filter or signal conditioning, if required, between the multiplexer and the ADC. This means that one antialiasing filter can be used for all eight channels. Connection of an external capacitor allows the user to adjust the time given to the multiplexer settling to include any external delays in the filter or signal conditioning circuitry.

• Fast 12bit ADC with 5.9μs conversion time
• Selection of input ranges: ±10V
• Allows separate access to multiplexer and ADC
• On-chip track/hold amplifier
• On-chip reference
• High-speed, flexible, serial interface
• Single supply, low-power operation (50 mW maximum)
• Power-down mode (75μW typ), ±1LSB linearity error
• 24 lead DIP package
• Operating temperature range from -55 to 125°C
