LTC1605ACSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1605ACSW#TRPBF 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 includes an internal sample-and-hold, precision reference, switched-capacitor SAR architecture, and trimmed internal clock. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2.0 LSB, guaranteed no missing codes, and a signal-to-noise ratio of 87.5 dB at 1kHz input. It utilizes a microprocessor-compatible 16-bit parallel output interface.

Analog To Digital Converters (ADC) Feature Summary

• Microprocessor-compatible 16-bit parallel output with BYTE select for byte-mode reading

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Multiplexed data acquisition systems
• High-speed data acquisition for personal computers
• Digital signal processing applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the SW (28-Lead Plastic SO Wide) designation in the ordering information. Confirm the temperature grade corresponds to the 'A' suffix (0°C to 70°C). Ensure the '#TRPBF' suffix indicates tape and reel packaging with lead-free finish. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 100ksps throughput are required within a single 5V supply constraint. The internal reference simplifies design if ±2.0 LSB INL accuracy is sufficient; otherwise, utilize the REF pin for an external reference. Consider the 20kΩ input impedance and ±10V range when designing the analog front-end driver circuitry.

Analog To Digital Converters (ADC) Part Context

The LTC1605 series serves as an improved second source for the ADS7805 and AD976. The AC variant specifies the commercial temperature range (0°C to 70°C), while the ISW variant covers the industrial range (-40°C to 85°C). The SW package provides a wide-body surface-mount option compared to the SSOP or PDIP packages.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitutes include the ADS7805 and AD976, which are noted as predecessors in the datasheet. Verify pin compatibility and performance specifications against the specific requirements before substitution.
