LTC1605-1CN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605-1CN#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 and dissipates typically 55mW. The device integrates a sample-and-hold circuit, precision reference, switched-capacitor successive approximation A/D converter, and trimmed internal clock. It features a unipolar input range of 0V to 4V and provides a microprocessor-compatible 16-bit parallel output port with control signals for easy interface to DSPs and microprocessors.

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 application requirements, as this part uses a 28-lead PDIP package which is marked obsolete in some contexts. Confirm the temperature range meets system specifications, as the 'C' suffix indicates a commercial range of 0°C to 70°C. Ensure the unipolar input specification aligns with the signal source characteristics before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1605-1 variant for unipolar inputs (0V to 4V); use LTC1605-2 for bipolar inputs (±4V). The 'CN' suffix denotes a 28-lead PDIP package with a commercial temperature range (0°C to 70°C). For industrial temperatures (-40°C to 85°C), select the 'IN' suffix. External references may be used if greater accuracy over temperature is required beyond the internal 2.5V reference capabilities.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1605 family of low-power, high-resolution ADCs. It is designed for applications requiring precise data conversion with minimal power consumption. The device simplifies system design by integrating necessary support functions like clocks and references on-chip, reducing external component count compared to discrete solutions.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-for-pin replacements within the same package and electrical specifications should be verified against current manufacturer availability lists. Since the PDIP package is noted as obsolete, alternative packages such as SSOP (e.g., LTC1605-1IG#PBF) may require schematic and layout modifications.
