LTC6360CMS8E#TRPBF

Overview

The LTC6360CMS8E#TRPBF 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 settles to 16-bit accuracy within 150ns for a 4V step at unity gain. The device operates on a single 5V supply but achieves true zero output swing 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 in a 3MHz bandwidth. It is housed in an 8-lead MSOP package with an exposed pad.

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 time for accurate data conversion
• Delivers ultra-low noise performance suitable for high-resolution signal processing applications

Applications

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

Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube packaging. Confirm the CMS8E designation corresponds to the commercial temperature range (0°C to 70°C) as opposed to industrial or extended grades. Ensure the component matches the 8-lead MSOP package with exposed pad physical dimensions specified in the datasheet.

Selection Notes

Select this component when a single-supply solution is required that must drive signals down to ground without external negative rails. Consider the 1GHz gain-bandwidth product and 150ns settling time for high-speed acquisition systems. Evaluate the 2.3nV/√Hz noise density against system noise budgets for high-resolution measurements.

Part Context

This part belongs to the LTC6360 family of single-ended SAR ADC drivers. It shares core architecture with variants like the IMS8E and HMS8E, differing primarily in temperature grade and packaging options. The series is characterized by its ability to maintain linearity and low distortion while swinging to true zero on a single supply.
