LTC1096IN8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1096IN8#PBF is an 8-bit micropower successive approximation analog-to-digital converter (ADC) in an 8-lead plastic DIP package. It operates on a single supply voltage ranging from 3V to 9V and draws 80μA during conversion, dropping to 1nA in shutdown mode. The device features a differential analog input, an external reference input, and a 3-wire serial interface for data transfer. Key electrical specifications include a maximum total unadjusted error of ±1.0 LSB over the temperature range, a sample rate up to 33kHz, and a conversion time of 16μs at 500kHz clock frequency.

Analog To Digital Converters (ADC) Feature Summary

• Micropower consumption: 80μA active, 1nA shutdown
• Single-supply operation: 3V to 9V
• Differential analog input with external reference
• 3-wire serial interface compatible with microprocessors

Analog To Digital Converters (ADC) Applications

• Battery-operated systems
• Remote data acquisition
• Battery monitoring and gas gauges
• Temperature measurement
• Isolated data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the application requirements, as this part number specifies an 8-lead Plastic DIP (N8). Confirm that the operating voltage range of 3V to 9V aligns with the system power supply. Ensure the external reference voltage is within the specified limits for accurate performance. Check for lead-free compliance if required by environmental standards.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1096 variant when a differential input and external reference are needed, as opposed to the multiplexed LTC1098. Consider the 3V to 9V supply range; for lower voltage applications (2.65V–4V), the LTC1096L series is appropriate. Verify that the 8-bit resolution and 33kHz sampling rate meet the system bandwidth requirements. Ensure the serial interface timing constraints are satisfied by the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1096 family of micropower 8-bit ADCs. The 'I' suffix indicates an industrial temperature range of –40°C to 85°C. The 'N8' designation specifies the 8-lead Plastic DIP package. The '#PBF' suffix denotes a lead-free finish and RoHS compliance. It is functionally similar to the SOIC-packaged LTC1096IS8 but differs in physical footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1096CS8#PBF offers the same electrical characteristics in an 8-lead SOIC package. For lower voltage applications, the LTC1096LCN8#PBF supports 2.65V to 4V operation. The LTC1098IN8#PBF provides a 2-channel multiplexer instead of a differential input.
