LTC6360CDD#TRPBF

Overview

The LTC6360CDD#TRPBF is a single-channel, high-speed operational amplifier designed as a driver for SAR ADCs. It operates on a single 5V supply with an input common mode range of 0V to 4.25V and output swing from -0.48V to 4.91V. Key electrical parameters include a gain-bandwidth product of 1 GHz, a slew rate of 135 V/µs (rising), and an input offset voltage maximum of 900 µV. The device features a total supply current of 17.5 mA typical and includes a low-noise charge pump generating approximately -0.6V at the CPO pin. It is housed in an 8-lead DFN package.

Feature Summary

• Integrates a low-noise on-chip charge pump to generate a negative bias rail, enabling true zero output swing on a single positive supply.
• Features very low input voltage noise density of 2.3 nV/√Hz combined with high linearity and low harmonic distortion.
• Supports fast settling times to 16-bit levels within 150ns for a 4V step, suitable for high-speed data acquisition systems.

Applications

• Driving single-ended high-performance successive approximation register (SAR) analog-to-digital converters
• High-speed buffer amplifiers in signal processing chains
• Low noise signal conditioning circuits requiring true zero output swing

Procurement Notes

Verify the specific temperature grade suffix matches the application requirements, as the DD package variant covers 0°C to 70°C while IDD and HDD variants extend to higher temperatures. Confirm the lead-free finish and tape-and-reel packaging specifications align with automated assembly processes. Ensure the ordering information corresponds to the exact performance characteristics required for the design.

Selection Notes

Select this component when driving SAR ADCs requires a single-supply solution with output swing extending below ground without external negative supplies. Consider the 1 GHz gain-bandwidth product and 135 V/µs slew rate for high-frequency signal integrity. Evaluate the 2.3 nV/√Hz noise density against system noise budgets. Verify that the 8-lead DFN package fits the available PCB real estate and thermal constraints.

Part Context

The LTC6360 belongs to Analog Devices' family of precision amplifier ICs designed for data converter interfaces. It replaces traditional two-component solutions consisting of a separate amplifier and an inverting charge pump. This integration reduces part count, board space, and electromagnetic interference while maintaining high linearity and low noise performance essential for modern high-resolution data acquisition systems.

Replacement Considerations
