Linear Technology announces the LT1994, a fully differential amplifier for driving high-resolution A/D converters. With guaranteed operation down to 2.375 V and rail-to-rail outputs, the differential amplifier can directly drive 2.5 V and 3 V SAR ADCs without the need of a negative supply. Achieving 94 dBc harmonic distortion at 1 MHz and a low voltage noise of 3 nV/square rootHz, the LT1994 provides wide dynamic range on low supply voltage. Suited for driving 14-bit to 16-bit ADCs, the LT1994 is an appropriate choice for general-purpose differential signal amplification, level shifting, single-ended to differential conversion and differential line driver/receiver applications in industrial, instrumentation and medical applications.
