s Single Supply 5V Operation s Power Shutdown After Each Conversion (LTC1297) s Built-In Sample-and-Hold s 60kHz Maximum Throughput Rate (LTC1292) s Direct 3-Wire Interface to Most MPU Serial Ports and All MPU Parallel Ports s Analog Inputs Common Mode to Supply Rails U KEY SPECIFICATIO S s Resolution: 12 Bits s Fast Conversion Time: 12µs Max Over Temp s Low Supply Current: 6.0mA s Shutdown Supply Current: 5µA (LTC1297) DESCRIPTIO The LTC®1292/LTC1297 are data acquisition systems that contain a 12-bit, switched-capacitor successive approximation A/D, a differential input, sample-and-hold on the (+) input, and serial I/O. When the LTC1297 is idle between conversions it automatically powers down reducing the supply current to 5µA, typically. All these features are packaged in an 8-pin DIP and are made possible using LTCMOSTM switched-capacitor technology. Because of their accuracy, ease of use and small package size these devices are well suited for digitizing analog signals in...
