LTC6360 Very Low Noise Single-Ended SAR ADC Driver with True Zero Output Fea T Descrip T n Output Swings to True Zero on Single Supply The LTC 6360 is a very low noise, high precision, high n 2.3nV/Hz Noise Density speed amplifier suitable for driving SAR ADCs. The n Fast Settling Time: 150ns, 16-Bit, 4V Step LTC6360 features a total output noise of 2.3nV/Hz n 110dB SNR in 3MHz Bandwidth combined with 150ns settling time to 16-bit levels (A = 1). V n Low Distortion, HD = 103dBc and HD = 109dBc 2 3 While powered from a single 5V supply, the amplifier out - for 4V Output at 40kHz P-P put can swing to 0V while maintaining high linearity. This n Low Offset Voltage: 250V Max is made possible with the inclusion of a very low noise n Low Power Shutdown: 350A Max on-chip charge pump that generates a negative voltage n 3mm 3mm 8-Pin DFN and 8-lead MSOP Packages to bias the output stage of the amplifier, increasing the allowable negative voltage swing. a T The LTC6360 is available in a compact 3mm 3mm, 8-pin leadless DFN package and an 8-pin MSOP package n 16-Bit and 18-Bit SAR ADC Driver with exposed pad and operates over a 40C to 125C n High Speed Buffer Amplifiers temperature range. n Low Noise Signal Processing L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
