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 (AV = 1). n Low Distortion, HD2 = –103dBc and HD3 = –109dBc While powered from a single 5V supply, the amplifier out- for 4VP-P Output at 40kHz put can swing to 0V while maintaining high linearity. This n Low Offset Voltage: 250µV Max is made possible with the inclusion of a very low noise n Low Power Shutdown: 350µA 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 al owable negative voltage swing.
