LTC6360IMS8E#PBF

Overview

The LTC6360IMS8E#PBF is a single-supply, very low noise amplifier designed for driving SAR ADCs. It features a total output noise density of 2.3nV/√Hz and achieves a settling time of 150ns to 16-bit levels for a 4V step. The device operates on a single 5V supply but swings its output to true zero via an internal charge pump generating a negative bias voltage. Key electrical parameters include a maximum input offset voltage of 250µV, a gain-bandwidth product of 1GHz, and a signal-to-noise ratio of 110dB within a 3MHz bandwidth.

Feature Summary

• Enables true zero output swing on a single supply using an integrated low-noise charge pump
• Provides high precision with low offset voltage and fast settling characteristics
• Delivers ultra-low noise performance suitable for high-resolution data acquisition

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 suffix (I for -40°C to 85°C) against system requirements. Confirm package type matches the MSOP-8 footprint. Ensure ESD handling procedures are followed during assembly. Check datasheet for absolute maximum ratings regarding input current limits and short circuit duration.

Selection Notes

Select this component when driving high-resolution SAR ADCs requiring rail-to-rail output swing from a single supply. Consider the 2.3nV/√Hz noise density for sensitive front-end applications. Evaluate the 150ns settling time for high-speed sampling requirements. Verify that the 8-pin MSOP package fits the PCB layout constraints.

Part Context

This part belongs to the LTC6360 family of single-ended SAR ADC drivers. It shares core architecture with variants like the LTC6360HMS8E#PBF, differing primarily in guaranteed operating temperature ranges. The IMS8E designation specifically indicates the industrial temperature grade (-40°C to 85°C) in the MSOP-8 package.

Replacement Considerations

LTC6360HMS8E#PBF offers the same functionality with an extended temperature range up to 125°C.
