The SDM components are complete, pin-compatible, data acquisition systems housed in a hermetically sealed 1"-square leadless chip carrier or a 1.1"-square pin grid array. The SDM862 small package outlines and low power consumption provide an ideal data acquisition solution when space is at a premium.
The SDM862 devices comprise of an input multiplexer, instrumentation amplifier with selectable gains, sample/hold amplifier and A/D converter with microprocessor interface and three-state buffers.
The SDM family will accept unipolar or bipolar voltage inputs in the range 0 to +10V, ±5V and ±10V. For lowlevel signals, jumper-selectable gains of 10 or 100 can be applied. The number of input channels can be expanded by the addition of multiplexers. System integration is simplified by the microprocessor interface and the facility of the sample/hold amplifier being controlled directly by the SDM862 A/D converter.
