LTC1099CSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1099CSW#TRPBF is an 8-bit analog-to-digital converter (ADC) featuring a built-in sample-and-hold circuit, enabling conversion rates up to the full Nyquist limit without external holding components. Operating on a single 5V supply, it delivers a typical conversion time of 2.5µs with latched three-state digital outputs for direct processor interfacing. The device supports Read and Write-Read modes, includes an overflow output for cascading, and offers user-adjustable conversion timing via an external resistor. It is housed in a 20-lead wide SOIC package.

Analog To Digital Converters (ADC) Feature Summary

• Built-in Sample-and-Hold: Handles input frequencies up to 156kHz or slew rates of 2.5V/ms without external S/H circuits.
• Fast Conversion: Typical conversion time of 2.5µs with edge-sensitive internal timing.
• Flexible Interface: Supports RD and WR-RD modes with latched three-state outputs and an overflow pin for cascading.
• Adjustable Timing: Conversion time can be modified using an external resistor on the TC pin.

Analog To Digital Converters (ADC) Applications

• Microprocessor-compatible data acquisition systems
• Two-quadrant analog multipliers when paired with a DAC
• Signal processing applications requiring high-speed digitization

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging. Confirm the CS grade corresponds to the commercial temperature range of 0°C to 70°C. Ensure the 20-lead wide SOIC (SW) package dimensions match the target PCB footprint. Check RoHS compliance status as specified in the manufacturer's documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring an 8-bit resolution at speeds approaching the Nyquist limit. The internal S/H simplifies analog front-end design by eliminating external hold capacitors. Consider the user-adjustable TC pin if conversion speed needs to be optimized for power consumption or specific timing constraints. Ensure the reference voltage source can drive the internal resistive ladder effectively.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1099 family of high-speed 8-bit ADCs. The 'C' suffix denotes the commercial temperature range, while 'SW' specifies the 20-lead plastic small outline wide package. The '#TRPBF' suffix typically indicates tape and reel packaging with lead-free finish, distinguishing it from tube-packaged variants like the CN.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications against alternative 8-bit parallel ADCs if sourcing this specific variant is restricted.
