LTC1092CN8#PBF

LTC1092CN8#PBF is a 10bit serial I/O data acquisition system. It is designed to provide complete function, excellent accuracy, and ease of use when digitizing analogue data from a wide variety of signal sources and transducers. Built around a 10bit, switched capacitor, successive approximation A/D core, these devices include software configurable analogue multiplexers and bipolar and unipolar conversion modes as well as on-chip sample and-holds. On-chip serial ports allow efficient data transfer to a wide range of microprocessors and microcontrollers. These circuits can provide a complete data acquisition system in ratiometric applications or can be used with an external reference in others. The high-impedance analogue inputs and the ability to operate with reduced spans (below 1V full scale) allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.

• Analog inputs common mode to supply rails, sample-and-holds
• 1 channel, unipolar conversion mode, reduced span capability
• Supply voltage range from 4.5V to 10V
• Clock frequency is 0.5MHz maximum at (VCC = 5V)
• Offset error is ±0.5LSB maximum at (TA = 25°C)
• Conversion time is 10CLK cycles typical at (TA = 25°C)
• Full-scale error is ±2.0LSB maximum at (TA = 25°C)
• Input capacitance is 65pF typical at (analogue inputs on-channel, TA = 25°C)
• Positive supply current is 1mA typical at (TA = 25°C)
• Operating temperature range from -40°C to 85°C, 8-lead PDIP package
