Overview

  • Output Swings to True Zero on Single Supply
  • 2.3nV/√Hz Noise Density
  • Fast Settling Time: 150ns, 16-Bit, 4V Step
  • 110dB SNR in 3MHz Bandwidth
  • Low Distortion, HD2 = –103dBc and HD3 = –109dBc for 4VP-P Output at 40kHz
  • Low Offset Voltage: 250μV Max
  • Low Power Shutdown: 350μA Max
  • 3mm × 3mm 8-Pin DFN and 8-lead MSOP Packages

The LTC6360 is a very low noise, high precision, high speed amplifier suitable for driving SAR ADCs. The LTC6360 features a total output noise of 2.3nV/√Hz combined with 150ns settling time to 16-bit levels (AV = 1).

While powered from a single 5V supply, the amplifier output can swing to 0V while maintaining high linearity. This is made possible with the inclusion of a very low noise on-chip charge pump that generates a negative voltage to bias the output stage of the amplifier, increasing the allowable negative voltage swing.

The LTC6360 is available in a compact 3mm × 3mm, 8-pin leadless DFN package and an 8-pin MSOP package with exposed pad and operates over a –40°C to 125°C temperature range.

Applications

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