LTC6360IMS8E#TRPBF

Overview

The LTC6360IMS8E#TRPBF 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 and settles to 16-bit levels in 150ns with a 4V step at unity gain. The device operates on a single 5V supply but swings its output to true zero via an internal charge pump generating approximately -0.6V. Key electrical parameters include a maximum input offset voltage of 250µV (MS8E), a signal-to-noise ratio of 110dB within a 3MHz bandwidth, and harmonic distortion of HD2 = –103dBc and HD3 = –109dBc for a 4VP-P output at 40kHz. It is available in an 8-lead MSOP package.

Feature Summary

• Integrates a low-noise on-chip charge pump to enable true zero output swing on a single positive supply
• Provides high-speed performance with fast settling time and wide bandwidth for accurate data acquisition
• Features low offset voltage and low power shutdown mode for precision applications

Applications

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

Procurement Notes

Verify the specific temperature grade suffix matches the application requirements. The IMS8E designation indicates an industrial temperature range of –40°C to 85°C. Ensure the tape and reel packaging format aligns with automated assembly equipment specifications. Confirm that the exposed pad connection is properly grounded on the PCB layout to maintain thermal and electrical performance.

Selection Notes

Select this component when driving SAR ADCs requires output swing down to ground without dual supplies. The device is optimized for unity gain buffering but supports gains up to five with external compensation networks. Consider the 8-lead MSOP package for compact designs requiring an exposed pad for thermal dissipation. Verify that the source impedance and feedback network values are chosen to minimize offset errors and ensure stability.

Part Context

This part belongs to the LTC6360 family of amplifiers designed specifically for interfacing with high-resolution analog-to-digital converters. The family includes variants with different temperature grades and package options, such as DFN and MSOP. The IMS8E variant specifically utilizes the 8-lead plastic MSOP package with an exposed pad, offering a balance of thermal performance and small footprint for dense circuit board layouts.
