LTC1091MJ8

The LTC1091MJ8 10-bit data acquisition system is designed to provide complete function, excellent accuracy and ease of use when digitiz-ing analog data from a wide variety of signal sources and transducers. Built around a 10-bit, switched capacitor,successive approximation A/D core, this devices includes software configurable analog multiplexers and bipolar and unipolar conversion modes as well as on-chip sample-and-holds. On-chip serial ports allow efficient data trans-fer to a wide range of microprocessors and microcontrol-lers. These circuits can provide a complete data acquisi-tion system in ratiometric applications or can be used withan external reference in others.

Features of the LTC1091MJ8 are:(1)programmable features:unipolar/bipolar conversions and differential/single-ended multiplexer configurations; (2)sample-and-holds; (3)single supply 5V, 10V or ±5V operation; (4)direct 3- or 4-wire interface to most MPU serial ports and all mpu parallel I/O ports; (5)analog inputs common mode to supply rails resolution: 10 bits; (6)total unadjusted error (A grade): ±1LSB over temp; (7)fast conversion time: 20s; (8)low supply current LTC1091: 3.5mA Max, 1.5mA typ.

The absolute maximum ratings of the LTC1091MJ8 can be summarized as:(1)lead temperature (soldering, 10 sec.):300°C;(2)storage temperature range:-65°C to 150°C;(3)operating temperature range:-40°C to 85°C;(4)power dissipation:500 mW;(5)supply voltage (Vcc) to GND or V-:12 V;(6)negative supply voltage (V-):-6V to GND.
