ALD2303A - DUAL PRECISION MICROPOWER CMOS VOLTAGE COMPARATOR WITH DRIVER

GENERAL DESCRIPTION
The ALD1712 is a monolithic precision operational amplifier intended primarily for a wide range of analog applications in +5V single power supply and ±5V dual power supply systems as well as +6V to 12V battery operated systems. All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process and is available as a standard cell in ALD's ASIC "Function-Specific" library.
The device has an input stage that operates to +300mV above and -300mV below the supply voltages with no adverse effects and/or phase reversals.
The ALD1712 has been developed specifically with the 5V single supply or ±2.5V dual supply user in mind. Several important characteristics of the device make many applications easy to implement for these supply voltages. First, the operational amplifier can operate with rail-to-rail input and output voltages. This feature allows numerous analog serial stages to be implemented without losing operating voltage margin. Secondly, the device was designed to accommodate mixed applications where digital and analog circuits may work off the same 5V power supply. Thirdly, the output stage can drive up to 400pF capacitive, and 1KW resistive loads in non-inverting unity gain connection, and up to 4000pF at a gain of 5. These features, coupled with extremely low input currents, high voltage gain, useful bandwidth of 1.5MHz, slew rate of 2.1V/ms, low power dissipation, low offset voltage and temperature drift, make the ALD1712 a truly versatile, user friendly, operational amplifier.
On-chip offset voltage trimming allows the device to be used without nulling in most applications. The device offers typical offset drift of less than 5mV/ °C which eliminates many trim or temperature compensation circuits. For precision applications, the 1712 is designed to settle to 0.01% in 8ms. The unique characteristics at input and output are modeled in an available macromodel.

ALD1712A - RAIL-TO-RAIL PRECISION OPERATIONAL AMPLIFIER

GENERAL DESCRIPTION
The ALD2704 is a dual monolithic operational amplifier with MOSFET input that has rail-to-rail input and output voltage ranges. The input voltage range and output voltage range are very close to the positive and negative power supply voltages. Typically the input voltage can be
beyond positive power supply voltage V+ or the negative power supply voltage V- by up to 300mV. The output voltage swings to within 60mV of either positive or negative power supply voltages at rated load.
With high impedance load, the output voltage of the ALD2704 approaches within 1mV of the power supply rails. This device is designed as an alternative to the popular J-FET input operational amplifier in applications where lower operating voltages, such as 9V battery or ±3.25V to ±6V power supplies are being used. The ALD2704 offers high slew rate of 5V/ms. It is designed and manufactured with Advanced Linear Devices' standard enhanced ACMOS silicon gate CMOS process, and it offers low unit cost and exceptional reliability.
The rail-to-rail input and output feature of the ALD2704 expands signal voltage range for a given operating supply voltage and allows numerous analog serial stages to be implemented without losing operating voltage margin. The output stage is designed to drive up to 10mA into 400pF
capacitive and 1.5KW resistive loads at unity gain and up to 4000pF at a gain of 5. Short circuit protection to either ground or the power supply rails is at approximately 15mA clamp current. Due to complementary output stage design, the output can source and sink 10mA into a load with symmetrical drive and is ideally suited for applications where push-pull voltage drive is desired.
For each of the operational amplifier, the offset voltage is trimmed on-chip to eliminate the need for external nulling in many applications. For precision applications, the output is designed to settle to 0.1% in 2ms. In large signal buffer applications, the operational amplifier can function as an ultrahigh input impedance voltage follower/buffer that allows input and output voltage swings from positive to negative supply voltages. This feature is intended to greatly simplify systems design and eliminate higher voltage power supplies in many applications.
