LTC6360HDD#PBF

Overview

The LTC6360HDD#PBF is a very low noise, high precision, high speed amplifier suitable for driving SAR ADCs. It features a total output noise of 2.3nV/√Hz combined with a 150ns settling time to 16-bit levels at unity gain. While powered from a single 5V supply, the amplifier output can swing to 0V while maintaining high linearity due to an on-chip charge pump generating a negative bias voltage. The device operates over a –40°C to 125°C temperature range and is housed in a compact 3mm × 3mm, 8-lead plastic DFN package.

Feature Summary

• Output swings to true zero on a single supply via internal charge pump
• Very low noise density of 2.3nV/√Hz
• Fast settling time of 150ns to 16-bit resolution
• Low offset voltage with maximum 250µV specification

Applications

• 16-Bit and 18-Bit SAR ADC Driver
• High Speed Buffer Amplifiers
• Low Noise Signal Processing

Procurement Notes

Verify the specific ordering suffix DD#PBF corresponds to the 8-Lead (3mm × 3mm) Plastic DFN package with an operating temperature range of –40°C to 125°C. Confirm that the lead-free finish matches the LFQT marking requirement. Ensure the procurement channel provides valid documentation for the Analog Devices manufacturer source.

Selection Notes

Select this component when driving SAR ADCs requires output swing down to ground using a single 5V supply. The integrated charge pump eliminates the need for external negative rail generation. Consider the 3mm × 3mm DFN package for space-constrained designs requiring operation up to 125°C ambient temperature.

Part Context

This part belongs to the LTC6360 family of amplifiers designed specifically for interfacing with high-resolution analog-to-digital converters. The 'H' designation indicates the extended industrial temperature grade (-40°C to 125°C), while 'DD' specifies the 8-lead DFN package format.

Replacement Considerations

LTC6360IDD#PBF offers the same package but with a limited temperature range of –40°C to 85°C.
