LTC1598

The LTC®1598 is an 8-channel, 5V micropower, 12-bit sampling A/D converter. It typically draws only 320mA 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.

On-chip serial ports allow efficient data transfer to a wide range of microprocessors and microcontrollers over three or four wires. This, coupled with micropower consumption, makes remote location possible and facilitates transmitting data through isolation barriers.

The circuit can be used in ratiometric applications or with an external reference. The high impedance analog inputs and the ability to operate with reduced spans (to 1.5V full scale) allow direct connection to sensors and transducers in many applications, eliminating the need for gain stages.
