LTC6363 Precision, Low Power Rail-to-Rail Output Differential Op Amp FEATURES DESCRIPTION n 100V Max Offset Voltage The LTC 6363 is a low power, low noise, fully differential n 50nA Max Input Offset Current op amp with rail-to-rail outputs optimized to drive low n Fast Settling: 780ns to 18-Bit, 8V Output power SAR ADCs. The LTC6363 draws only 1.9mA supply P-P n 1.9mA Supply Current current in active operation and features a shutdown mode n 2.9nV/Hz Input-Referred Noise which reduces the current consumption to 20A (V = 3V). S n 2.8V (1.4V) to 11V (5.5V) Supply Voltage Range The amplifier may be configured to convert a single-ended n Differential Rail-to-Rail Outputs input signal to a differential output signal or may be driven n Input Common Mode Range Includes Ground differentially. Low offset voltage and low input offset current n Low Distortion: 115dB SFDR at 2kHz, 18V PP make this amplifier suitable for use not only as an ADC n 500MHz Gain-Bandwidth Product driver but also earlier in the signal chain to provide filtering, n 35MHz 3dB Bandwidth gain or even attenuation by up to 10-to-1 to convert high n Low Power Shutdown: 20A (V = 3V) S voltage signals to levels suitable for low voltage ADCs. n 8-lead MSOP and 2mm 3mm 8-Lead DFN Packages The LTC6363 is available in 8-lead MSOP and 2mm 3mm leadless DFN packages, and operates with guaranteed APPLICATIONS specifications over a 40C to 125C temperature range. n 20-Bit, 18-Bit and 16-Bit SAR ADC Drivers L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
