LTC1099AIN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1099AIN#PBF is an 8-bit analog-to-digital converter featuring a built-in sample-and-hold circuit. It operates on a single 5V supply and supports parallel data output with three-state control. The device offers two interface modes: Read (RD) mode for processor integration and Write-Read (WR-RD) mode for standalone or direct control applications. Key specifications include a typical conversion time of 2.5µs, a maximum power dissipation of 75mW, and a total unadjusted error of -0.75 LSB. The component is housed in a 20-lead PDIP package and functions within an ambient temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Built-in Sample-and-Hold with 2.5V/ms tracking rate
• Two operational modes: RD and WR-RD
• Latched three-state digital outputs
• Overflow output (OFL) for cascading

Analog To Digital Converters (ADC) Applications

• Microprocessor-compatible data acquisition systems
• Standalone A/D conversion tasks
• Cascaded configurations for higher resolution

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific 'AI' suffix designation against official Analog Devices documentation to confirm the extended industrial temperature range (-40°C to +85°C). Ensure that the 20-lead PDIP physical dimensions match the target PCB footprint requirements before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an integrated sample-and-hold is required to simplify external circuitry. The user-adjustable conversion time via Pin 19 allows optimization for specific throughput needs. Verify that the parallel interface timing aligns with the host system's clock constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1099 family of high-speed microprocessor-compatible ADCs. The 'A' grade indicates tighter accuracy specifications compared to the standard 'C' grade, while the 'I' suffix denotes the industrial temperature rating. The '#PBF' suffix confirms lead-free packaging compliant with RoHS standards.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the LTC1099CN and LTC1099ACN. Note that these variants differ in temperature range and accuracy specifications. No other cross-model substitutes are confirmed by public documentation.
