LTC1605ISW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605ISW#PBF 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, precision reference, switched-capacitor SAR architecture, and trimmed internal clock. It offers guaranteed no missing codes over temperature, with maximum integral nonlinearity (INL) of ±2.0LSB. The ADC provides a microprocessor-compatible 16-bit parallel output port with control signals for easy integration into data acquisition systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the SW (SO Wide) variant when sourcing replacements. Confirm the temperature grade corresponds to the 'I' suffix for industrial range (-40°C to +85°C). Ensure the '#PBF' suffix indicates lead-free finish compliance if required by assembly specifications. Cross-reference pinout compatibility if substituting with older ADS7805 or AD976 designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and low power in a single-supply environment. The internal reference simplifies design but external references may be used for enhanced accuracy. Consider the parallel interface requirements and ensure the host system can handle the 16-bit data bus. Verify that the ±10V input range aligns with sensor output levels without additional scaling circuitry.

Analog To Digital Converters (ADC) Part Context

The LTC1605 series includes variants in SSOP and SO Wide packages. The ISW#PBF designation specifically identifies the industrial temperature grade version housed in a 28-lead plastic SO Wide package. This part serves as an improved second source for legacy components like the ADS7805 and AD976, offering comparable performance with modern manufacturing processes.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitutes include the ADS7805 and AD976, though these are legacy parts. Direct pin-for-pin replacement requires verifying voltage levels and timing characteristics against the original design constraints.
