Product Introduction
A low power, low noise differential driver for analog-to-digital converters (ADCs) up to 18 bits in systems that are sensitive to power. Configured in an easy-to-use, single-ended-to-differential configuration and requires no external components for a gain of 2 configuration. A resistive feedback network can be added to achieve gains greater than 2. Provides essential benefits, such as low distortion and high SNR that are required for driving high resolution ADCs.
With a wide input voltage range (0 V to 3.9 V on a single 5 V supply), rail-to-rail output, high input impedance, and a user-adjustable gain, designed to drive single-supply ADCs with differential inputs found in a variety of low power applications, including battery-operated devices and single-supply data acquisition systems.
Ideal for driving the 16-bit and 18-bit PulSAR ADCs, such as the AD7687, AD7690, and AD7691.
Manufactured on a proprietary, second-generation, eXtra fast complementary bipolar (XFCB) process, which enables the amplifier to achieve 18-bit performance on low supply currents.
Available in a small 8-lead LFCSP as well as a standard 8-lead SOIC and is rated to work over the extended industrial temperature range, -40°C to +125°C.
