LTC1867AIGN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1867AIGN#PBF is a low-power, 16-bit, 8-channel analog-to-digital converter (ADC) from Analog Devices. It features a sampling rate of 200ksps and operates on a single 5V supply (4.75V to 5.25V). The device includes an internal 2.5V reference, an 8-channel multiplexer supporting single-ended or differential inputs, and SPI/MICROWIRE serial I/O. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 89dB, ±2.5LSB maximum Integral Nonlinearity (INL), and a power dissipation of 6.5mW at full speed. It is housed in a 16-pin narrow SSOP package and supports an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 8-channel analog input multiplexer with configurable single-ended or differential modes
• Low power consumption with automatic nap mode between conversions
• On-chip precision internal voltage reference
• Simple serial interface compatible with standard digital protocols

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• High-speed data acquisition applications
• Battery-operated portable equipment
• Multiplexed sensor networks
• Imaging systems requiring multi-channel input

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the IGN suffix matches the required industrial temperature grade (-40°C to +85°C). Ensure the order quantity aligns with tube packaging constraints if applicable. Cross-reference the manufacturer's latest documentation for any potential product change notifications affecting pinout or electrical characteristics before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high resolution (16-bit) and moderate speed (200ksps) are required for multi-channel sensing. The integrated multiplexer reduces external switching components. Consider the internal reference for cost-sensitive designs; however, external references may be needed for superior drift performance. Evaluate power budgets carefully, as nap mode offers significant savings at lower throughput rates compared to continuous conversion.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1863/LTC1867 family of pin-compatible ADCs. The LTC1867 provides 16-bit resolution, whereas the LTC1863 offers 12-bit resolution. Both share identical pinouts and functionality, allowing for design flexibility during prototyping or production scaling. The 'A' grade typically denotes tighter linearity specifications compared to standard grades.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1863 is a pin-compatible alternative offering 12-bit resolution. For automotive applications, consider the LTC1867IGN#WPBF variant which meets AEC-Q100 qualification standards. Verify that any substitute maintains the same 16-pin SSOP footprint and voltage requirements.
