LTC1605ACSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605ACSW#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 circuit, precision reference, switched-capacitor SAR architecture, and trimmed internal clock. Key specifications include ±2.0LSB maximum integral nonlinearity (INL), guaranteed no missing codes, and a signal-to-noise ratio of 86dB. It utilizes a microprocessor-compatible parallel output interface.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 100ksps sampling rate
• Single 5V supply operation with 55mW typical power dissipation
• ±10V bipolar input range with internal ±2.5V reference
• Microprocessor-compatible 16-bit or two-byte parallel output

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 ordering suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the AC suffix corresponds to the commercial temperature range (0°C to 70°C). Ensure the SW package designation matches the required 28-lead plastic SO Wide footprint for the target PCB design.

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 ±2.0LSB INL is sufficient; otherwise, an external reference may be used for enhanced accuracy. The parallel interface requires appropriate microprocessor or DSP connections.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1605 family of high-resolution ADCs. The AC suffix denotes the commercial temperature grade (0°C to 70°C), while the ISW variant covers the industrial range (-40°C to 85°C). The SW package is a 28-lead plastic SO Wide, distinct from the SSOP or PDIP options available in the same series.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet identifies the LTC1605 as an improved second source for the ADS7805 and AD976. Verify pinout compatibility and electrical parameter alignment before substituting these legacy parts.
