DESCRIPTION
The LTC®1598 is an 8-channel, 5V micropower, 12-bit sampling A/D converter. It typically draws only 320µA of supply current when converting and automatically powers down to typically 1nA between conversions. The LTC1598 is available in a 24-pin SSOP package and operates on a 5V supply. The 12-bit, switched-capacitor, successive approximation ADC includes an 8-channel MUX and a sample-and-hold.
