Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The #PBF suffix indicates lead-free finish. Confirm availability status through authorized distributors as supply levels may vary. Ensure the selected variant matches the required operating temperature range for the application environment.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1605AIG#PBF for industrial applications requiring –40°C to +85°C operation in a 28-lead SSOP package. Use the external reference capability if higher accuracy than the internal 2.5V bandgap reference is required. Ensure the driving source impedance is low enough to meet the acquisition time requirements for optimal dynamic performance.

Analog To Digital Converters (ADC) Part Context

The LTC1605AIG#PBF belongs to the LTC1605 family of 16-bit sampling ADCs. It serves as an improved second source alternative to legacy parts such as the ADS7805 and AD976. The 'A' grade designation ensures tighter linearity specifications compared to standard grades, while the 'I' suffix denotes the industrial temperature range.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet identifies the LTC1605 as an improved second source to the ADS7805 and AD976. Verify pin compatibility and timing parameters when substituting these legacy components.
