The LTC1298CN8#PBF is a 12-bit, 2-channel analog-to-digital converter from Analog Devices featuring a multiplexed successive approximation architecture. It achieves a sampling rate of 11.1k SPS and communicates via a simple SPI interface. The device operates with an external reference and is specified for 0°C to 70°C. Housed in a compact 8-pin DIP package, it is well-suited for battery-powered instruments, industrial sensors, and general-purpose data acquisition systems requiring precise, low-power signal digitization.
- Low Power Consumption: Ideal for battery-operated devices, the LTC1298CN8#PBF minimizes energy draw while maintaining 12-bit accuracy.
- Flexible Input Multiplexing: The 2-channel MUX supports both differential and single-ended inputs, simplifying sensor interface design.
- Simple SPI Interface: Easy integration with most microcontrollers, reducing firmware complexity and board space.
- Ratiometric Measurement Capability: External reference input allows direct connection to sensor excitation, improving overall system accuracy.
Battery-Powered Instrumentation
The LTC1298CN8#PBF's low power consumption and 2-channel multiplexer make it ideal for portable battery monitors and handheld data loggers, where precise 12-bit conversion of voltage and current sense signals is required at sampling rates up to 11.1k SPS.
Industrial Process Control
In industrial automation, this ADC digitizes 4-20 mA loop signals or 0-10V sensor outputs. Its external reference input allows ratiometric measurements, improving accuracy in temperature and pressure monitoring systems.
Data Acquisition Systems
With its SPI interface and 2:1 MUX, the LTC1298CN8#PBF can be easily integrated into multi-channel DAQ front-ends. The 12-bit resolution at 11.1k SPS provides a good balance between speed and precision for general-purpose logging.
Sensor Signal Conditioning
For bridge sensors (strain gauges, load cells), the differential input capability of the 2-channel MUX allows direct connection to the sensor output, while the external reference can be tied to the bridge excitation for accurate ratiometric conversion.
Embedded Control Loops
In closed-loop motor control or power supply monitoring, the fast SPI interface (up to 11.1k SPS) enables real-time digitization of feedback signals, allowing the controller to respond quickly to changing conditions.
