The LM7321MF/NOPB is a single high output current Operational Amplifier with rail-to-rail input and output. The LM732xx family is efficient, achieving 18V/µs slew rate and 20MHz unity gain bandwidth while requiring only 1mA of supply current per op amp. The LM732xx device performance is fully specified for operation at 2.7V, ±5 and ±15V. The LM732xx device is designed to drive unlimited capacitive loads without oscillations. Greater than rail-to-rail input common-mode voltage range with 50dB of common-mode rejection across this wide voltage range, allows both high-side and low-side sensing. Most device parameters are insensitive to power supply voltage and this makes the parts easier to use where supply voltage may vary, such as automotive electrical systems and battery powered equipment. This amplifier has true rail-to-rail output and can supply a respectable amount of current (15mA) with minimal head-room from either rail (300mV) at low distortion (0.05% THD+noise).

The AD824 is a quad, FET input, single supply amplifier, featuring rail-to-rail outputs. The combination of FET inputs and rail-to-rail outputs makes the AD824 useful in a wide variety of low voltage applications where low input current is a primary consideration. The AD824 is guaranteed to operate from a 3 V single supply up to ±15 V dual supplies. AD824AR-3V parametric performance at 3 V is fully guaranteed. Fabricated on Analog Devices, Inc., complementary bipolar process, the AD824 has a unique input stage that allows the input voltage to safely extend beyond the negative supply and to the positive supply without any phase inversion or latch-up. The output voltage swings to within 15 mV of the supplies. Capacitive loads to 350 pF can be handled without oscillation.

The FET input combined with laser trimming provides an input that has extremely low bias currents with guaranteed offsets below 1 mV. This enables high accuracy designs even with high source impedances. Precision is combined with low noise, making the AD824 ideal for use in battery powered medical equipment. Applications for the AD824 include portable medical equipment, photo diode preamplifiers, and high impedance transducer amplifiers. The ability of the output to swing rail-to-rail enables designers to build multistage filters in single supply systems and maintain high signal-to-noise ratios. The AD824 is specified over the extended industrial (−40°C to +85°C) temperature range and is available in narrow 14-lead SOIC package.
