LTC1286CN8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1286CN8#PBF is a micropower, 12-bit successive approximation sampling analog-to-digital converter (ADC) housed in an 8-lead plastic DIP package. It operates on a single supply voltage ranging from 4.5V to 9V and typically draws 250µA of supply current when converting at a sampling rate of 12.5 ksps. The device features an internal sample-and-hold circuit and automatically powers down to a typical leakage current of 1nA when not performing conversions. It utilizes a serial interface compatible with SPI and Microwire protocols for data transfer.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with guaranteed maximum differential nonlinearity (DNL) of -3/4 LSB
• Single-ended or differential input configuration with on-chip sample-and-hold
• Micropower consumption: 250µA typical during conversion, 1nA typical in shutdown mode
• Serial I/O interface compatible with standard microprocessor communication protocols

Analog To Digital Converters (ADC) Applications

• Battery-operated systems requiring low power consumption
• Remote data acquisition networks
• Battery monitoring circuits
• Handheld terminal interfaces
• Temperature measurement systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix CN8 indicates the commercial temperature range (0°C to 70°C) and the N8 package style (8-lead PDIP). Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering part number matches the required pinout and thermal specifications for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1286CN8#PBF for applications requiring a single differential input channel and operation within the 0°C to 70°C temperature range. If a wider industrial temperature range (-40°C to 85°C) is required, consider the LTC1286IN8 variant. For designs needing two input channels, the LTC1298 series is the appropriate alternative. Ensure the system clock frequency does not exceed 200kHz for optimal performance at 5V supplies.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1286/LTC1298 family of micropower sampling ADCs manufactured by Analog Devices. The CN8 suffix denotes the commercial grade version packaged in an 8-lead plastic dual in-line package (PDIP). It serves as a low-cost, low-power solution for battery-powered instrumentation where minimal active current draw is critical.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1286IN8#PBF is the direct industrial temperature range equivalent. The LTC1285 provides a 3V version of this architecture. For multi-channel requirements, the LTC1298 series offers a software-selectable 2-channel multiplexer while maintaining similar power characteristics.
