LTC1099ACN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1099ACN#PBF is a high-speed, microprocessor-compatible 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features an internal sample-and-hold circuit that enables conversion rates up to the full Nyquist limit without external components. The device operates on a single 5V supply and offers a typical conversion time of 2.5µs. Key electrical specifications include a maximum power dissipation of 75mW, a total unadjusted error of -0.75 LSB, and latched three-state digital outputs. It supports parallel data interfaces and includes an overflow output for cascading applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component matches the specific AC grade (-0.75 LSB error) and N package (PDIP-20). Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering suffix corresponds to the tube packaging format if required for the assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring fast 8-bit conversion with integrated sampling capabilities. The AC grade provides tighter accuracy than the standard C grade. Consider the 2.5V/ms slew rate limit of the internal S/H when processing high-frequency signals. Verify that the parallel interface timing aligns with the target processor's read/write cycles.

Analog To Digital Converters (ADC) Part Context
