LTC1196-2ACS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1196-2ACS8#PBF is an 8-bit, 1Msps successive approximation register (SAR) analog-to-digital converter in an 8-lead SOIC package. It operates on a single supply voltage ranging from 2.7V to 6V, with power dissipation of 10mW at 3V and 50mW at 5V. The device features a differential analog input, allowing measurement of signals floating on DC common-mode voltages or operation with reduced spans below 1V full scale. It utilizes a 3-wire serial interface for data transfer and specifies a total unadjusted error of ±1/2 LSB maximum over the operating temperature range.

Analog To Digital Converters (ADC) Feature Summary

• High-speed 8-bit SAR ADC with sampling rates up to 1MHz
• Differential analog input configuration for flexible signal conditioning
• Low power consumption: 10mW at 3V, 50mW at 5V
• ±1/2 LSB total unadjusted error specification over temperature

Analog To Digital Converters (ADC) Applications

• Single 5V supply high-speed data acquisition systems
• Portable or compact instrumentation requiring low power
• Disk drive read channels
• Battery-operated systems with limited power budgets

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A' indicates the commercial temperature grade (0°C to 70°C) as defined in the manufacturer's ordering information. Confirm that the '#PBF' designation corresponds to lead-free finish and tube packaging. Ensure the source documentation explicitly supports these attributes for this exact part number before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1196-2 variant specifically for its differential input architecture, which supports inputs floating on DC common-mode voltages. This model is suitable when external reference pins are required, unlike the LTC1198 series. Verify that the system clock can support the required 14.4MHz frequency for maximum conversion speed if needed.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC1196/LTC1198 family of 8-bit, 1Msps ADCs designed for compact, high-speed applications. The LTC1196-2 differs from the LTC1198 by offering a dedicated differential input and external reference pin, whereas the LTC1198 includes a multiplexer and auto-shutdown feature. Both share the same core SAR architecture and SO-8 packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other Analog Devices SAR ADCs in the SO-8 package if pin compatibility is required, but functional equivalence must be verified against specific electrical parameters.
