LTC1605-1IG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605-1IG#PBF is a single-supply, 16-bit, 100ksps sampling analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates from a single 5V supply with typical power dissipation of 55mW. The device features an unipolar input range of 0V to 4V and includes an integrated sample-and-hold circuit, precision reference, switched-capacitor successive approximation ADC, and trimmed internal clock. It provides a microprocessor-compatible 16-bit parallel output port with control signals for easy interface to DSPs and microprocessors.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with no missing codes up to 15 bits
• Single 5V supply operation with 55mW typical power dissipation
• Unipolar input range: 0V to 4V
• Internal synchronized clock and precision reference

Analog To Digital Converters (ADC) Applications

• Industrial process control
• Multiplexed data acquisition systems
• High speed data acquisition for PCs
• Digital signal processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the 'I' grade designation specifies the industrial temperature range of –40°C to 85°C. Ensure the SSOP-28 package matches the target PCB footprint. Check current availability status as distribution may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-resolution conversion with low power consumption on a single 5V supply. The LTC1605-1 variant is suitable for unipolar signals (0V to 4V), while the LTC1605-2 handles bipolar inputs (±4V). Consider external references if higher accuracy over temperature is required beyond the internal bandgap specifications.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1605-1/LTC1605-2 family of low-power, 16-bit sampling ADCs. It is designed to replace older components like the ADS7805 and AD976 in industrial and data acquisition applications. The device integrates all necessary functions for a complete ADC solution on a single chip, simplifying board layout and design complexity.
