LTC1867ACGN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1867ACGN#PBF is a 16-bit, 8-channel analog-to-digital converter (ADC) from Analog Devices. It features a sampling rate of 200ksps and operates on a single 5V supply with a voltage range of 4.75V to 5.25V. The device includes an internal 2.5V reference and offers a signal-to-noise ratio of 89dB. It supports both unipolar and bipolar conversion modes with single-ended or differential inputs. Power consumption is 1.3mA at full speed, dropping to 150µA in nap mode. It is housed in a 16-lead narrow SSOP package and operates within a temperature range of 0°C to 70°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer supporting configurable single-ended or differential input connections.
• Features automatic nap mode between conversions to reduce power consumption in low-duty-cycle applications.
• Includes a precision internal bandgap reference with an output buffer for improved accuracy.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• High-speed data acquisition modules
• Battery-operated portable instrumentation
• Multiplexed sensor networks

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ACGN' corresponds to the commercial temperature grade (0°C to 70°C) and SSOP package. Confirm RoHS compliance status via the manufacturer's official documentation before procurement. Ensure the ordering part number matches the required lead-free finish specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-resolution 16-bit ADC is required with multiple input channels in a compact footprint. Consider the LTC1867ACGN#PBF over industrial grades if the application environment remains within the commercial temperature range. Evaluate the internal reference performance against external requirements for drift and noise sensitivity.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1863/LTC1867 family of pin-compatible ADCs. The LTC1867 variant provides 16-bit resolution compared to the 12-bit LTC1863. The 'A' designation indicates enhanced DC performance specifications, while 'C' denotes the commercial operating temperature range. The 'IGN' suffix would indicate the industrial temperature grade.

Analog To Digital Converters (ADC) Replacement Considerations

LTC1867CGN#PBF: Commercial grade without enhanced A-specifications. LTC1867IGN#PBF: Industrial temperature grade (-40°C to 85°C). LTC1863ACGN#PBF: Pin-compatible 12-bit resolution variant.
