LTC1605CN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605CN#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 provides a microprocessor-compatible 16-bit parallel output port with control signals for easy integration into data acquisition systems.

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 package type matches the required board layout, as the CN suffix indicates a 28-lead PDIP package. Confirm the operating temperature range meets system requirements, as the C suffix specifies 0°C to 70°C. Check for lead-free compliance if necessary, as indicated by the #PBF suffix. Ensure the source document confirms availability for this specific obsolete package variant.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1605CN#PBF when a through-hole 28-pin DIP package is required for prototyping or legacy designs. Choose the ISW or ICG variants for industrial temperature ranges (-40°C to 85°C). Consider the parallel interface requirements and ensure the host system can handle the 16-bit data bus timing. Verify that the ±10V input range aligns with the sensor signal levels.

Analog To Digital Converters (ADC) Part Context

The LTC1605 series includes various packages such as SSOP, SO Wide, and PDIP. The CN#PBF specifically denotes the 28-lead Plastic Dual In-Line Package (PDIP) with commercial temperature range (0°C to 70°C) and lead-free finish. This package is listed as obsolete in the datasheet order information section.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet identifies the LTC1605 as an improved second source to the ADS7805 and AD976. Designers replacing these parts should verify pin compatibility and electrical specifications against the LTC1605 datasheet.
