LTC1605ISW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1605ISW#TRPBF is a 16-bit, 100ksps sampling analog-to-digital converter (ADC) from Analog Devices. It operates on a single 5V supply with typical power dissipation of 55mW. The device features a ±10V bipolar input range and includes an internal sample-and-hold circuit, precision reference, and switched-capacitor SAR architecture. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2.0 LSB, guaranteed no missing codes across the operating temperature range, and a signal-to-noise ratio of 86dB typ. It utilizes a microprocessor-compatible parallel output interface.

• Single 5V supply operation with 55mW typical power consumption
• ±10V analog input range with ±25V overvoltage protection
• 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 that the #TRPBF suffix indicates tape and reel packaging, distinct from tube packaging. Confirm the ISW suffix corresponds to the 28-lead plastic SO Wide package and the -40°C to +85°C industrial temperature range. Ensure compatibility with existing board layouts for the SO Wide form factor.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit ADC with a wide ±10V input range is required without external attenuation networks. It serves as an improved second source for ADS7805 and AD976 devices. Consider the internal reference limitations if higher accuracy over temperature is needed, in which case an external reference should be used.

Analog To Digital Converters (ADC) Part Context

The LTC1605 series includes variants such as the LTC1605AIG#TRPBF and LTC1605AISW#PBF. The ISW variant specifically denotes the industrial temperature grade (-40°C to +85°C) and the SO Wide package. Other packages in the family include SSOP and PDIP, with different suffixes indicating lead-free finish and packaging type.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the ADS7805 and AD976. Verify pinout compatibility and electrical parameter alignment before substitution.
