LTC6360IDD#PBF

Overview

The LTC6360IDD#PBF is a single-ended SAR ADC driver amplifier manufactured by Analog Devices Inc. It operates on a single 5V supply and features an integrated low-noise charge pump to enable true zero output swing. Key electrical parameters include a noise density of 2.3nV/√Hz, a settling time of 150ns for a 4V step to 16-bit accuracy, and a maximum input offset voltage of 900µV. The device provides a signal-to-noise ratio of 110dB within a 3MHz bandwidth and supports a gain-bandwidth product of 1GHz.

Feature Summary

• Integrated low-noise charge pump enables output swing to true zero on a single supply
• High precision with fast settling time suitable for driving high-resolution SAR ADCs
• Low harmonic distortion characteristics for accurate signal processing
• Low power shutdown mode reduces total supply current significantly

Applications

• Driving 16-bit and 18-bit SAR ADCs
• High-speed buffer amplifiers
• Low noise signal processing circuits

Procurement Notes

Verify the specific temperature grade (I) and package type (DD-8 DFN) against the design requirements. Confirm that the –40°C to 85°C operating range aligns with the system environment. Ensure the ordering suffix matches the required tape and reel or tube packaging format as specified in the manufacturer's documentation.

Selection Notes

Select this component when a single-supply amplifier requires rail-to-rail output capability down to ground without external negative rails. Consider the 2.3nV/√Hz noise density and 1GHz gain-bandwidth product for high-frequency applications. Evaluate the 150ns settling time to ensure it meets the acquisition time constraints of the target ADC.

Part Context

This part belongs to the LTC6360 family of very low noise, high precision, high speed amplifiers designed specifically for driving SAR ADCs. The IDD suffix indicates the industrial temperature grade (-40°C to 85°C), while the DD suffix denotes the 8-lead (3mm × 3mm) plastic DFN package with an exposed pad.

Replacement Considerations

LTC6360CDD#PBF (Commercial temp), LTC6360HDD#PBF (Extended temp), LTC6360IMS8E#PBF (MSOP package). Verify temperature range and package compatibility before substitution.
