LTC1605-2IG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1605-2IG#PBF is a single-supply, 16-bit, 100ksps sampling analog-to-digital converter (ADC) from Analog Devices. It features a bipolar input range of ±4V and operates on a single 5V supply with typical power dissipation of 55mW. The device integrates a sample-and-hold circuit, precision reference, switched-capacitor successive approximation A/D core, and an internal clock. It provides a microprocessor-compatible 16-bit parallel output port with control signals including CS, R/C, and BUSY for easy interfacing with DSPs and microprocessors.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with 100ksps sampling rate
• Bipolar input range of ±4V
• Single 5V supply operation with 55mW typical power dissipation
• Internal synchronized clock and precision reference

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 specific ordering suffix #PBF indicates lead-free finish and RoHS compliance as per the manufacturer's standard marking conventions. Confirm the 'I' grade designation corresponds to the industrial temperature range of –40°C to +85°C. Ensure the SSOP-28 package matches the target PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1605-2 variant specifically for bipolar input applications requiring a ±4V range; the LTC1605-1 offers a unipolar 0V to 4V range. Consider using an external reference if greater accuracy over temperature is required beyond the internal bandgap specifications. Ensure the driving source impedance is low enough to meet the acquisition time requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1605 family of low-power, high-resolution ADCs. The -2 suffix denotes the bipolar input version, while the IG suffix indicates the industrial temperature grade. The #PBF suffix specifies the lead-free packaging option. It is part of Linear Technology's portfolio now under Analog Devices.
