LTC1605CSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605CSW#PBF is a 16-bit, 100ksps sampling analog-to-digital converter (ADC) from Analog Devices Inc. It operates on a single 5V supply with typical power dissipation of 55mW. The device features a ±10V bipolar input range and integrates a sample-and-hold circuit, precision reference, switched-capacitor SAR architecture, and an internal clock. It provides a microprocessor-compatible 16-bit parallel output interface with control signals for easy integration into data acquisition systems.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with guaranteed no missing codes over temperature
• 100ksps sampling rate with 55mW typical power consumption
• Bipolar input range of ±10V with internal or external reference options
• 28-lead SO Wide (SW) package

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 specific ordering suffix #PBF indicates lead-free finish and RoHS compliance as per manufacturer standards. Confirm the 'CS' suffix corresponds to the commercial temperature range (0°C to 70°C) and the 'SW' package type. Ensure compatibility with single 5V supply requirements for both analog and digital domains.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution at 100ksps is required with low power consumption. It is suitable for applications needing a ±10V input range without external scaling. Consider the internal reference accuracy; use an external reference if higher temperature stability is needed. Ensure the PCB layout supports separate analog and digital ground planes to minimize noise.

Analog To Digital Converters (ADC) Part Context

The LTC1605 series includes variants in SSOP, SW, and PDIP packages with different temperature grades (C for commercial, I for industrial). The CS variant specifically denotes the commercial temperature range (0°C to 70°C) housed in a 28-lead Plastic SO Wide package. This part serves as an improved second source for legacy parts like the ADS7805 and AD976.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly documented equivalents include the ADS7805 and AD976, which the LTC1605 is designed to improve upon. Verify pinout compatibility and electrical specifications such as input range and power supply requirements before substitution.
