GENERAL DESCRIPTION

Table 1. Low Power Op Amps

The AD8622 is a dual, precision rail-to-rail output operational

amplifier with a low supply current of only 350 μA maximum

over temperature and supply voltages. It also offers ultralow

offset, drift, and voltage noise combined with very low input

bias current over the full operating temperature range.

With typical offset voltage of only 10 μV, offset drift of 0.5 μV/°C,

and noise of only 0.2 ꢀV p-p (0.1 Hz to 10 Hz), it is perfectly

suited for applications where large error sources cannot be

tolerated. Many systems can take advantage of the low noise,

dc precision, and rail-to-rail output swing provided by the

AD8622 to maximize the signal-to-noise ratio and dynamic

range for low power operation. The AD8622 is specified for the

extended industrial temperature range of −40°C to +125°C and

is available in lead-free SOIC and MSOP packages.

APPLICATIONS INFORMATION

INPUT PROTECTION

= ±15V

The maximum differential input voltage that can be applied to

the AD8622 is determined by the internal diodes connected

across its inputs and series resistors at each input. These internal

diodes and series resistors limit the maximum differential input

voltage to 10 V and are needed to prevent base-emitter junction

breakdown from occurring in the input stage of the AD8622

when very large differential voltages are applied. In addition,

the internal resistors limit the currents that flow through the

diodes. However, in applications where large differential voltages

can be inadvertently applied to the device, large currents may

still flow through these diodes. In such a case, external resistors

must be placed at both inputs of the op amp to limit the input

currents to 10 mA (see Figure 52).

OUT

TIME (200µs/DIV)

Figure 53. No Phase Reversal

MICROPOWER INSTRUMENTATION AMPLIFIER

The AD8622 is a dual, high precision, rail-to-rail output op amp

operating at just 215 ꢀA quiescent current per amplifier. Its

ultralow offset, offset drift, and voltage noise, combined with its

very low bias current and high common-mode rejection ratio

(CMRR), are ideally suited for high accuracy and micropower

instrumentation amplifier.

500Ω

1/2

AD8622

Figure 54 shows the classic 2-op-amp instrumentation amplifier

with four resistors using the AD8622. The key to high CMRR

for this instrumentation amplifier are resistors that are well

matched from both the resistive ratio and the relative drift. For

true difference amplification, matching of the resistor ratio is

very important, where R3/R4 = R1/R2. Assuming perfectly

matched resistors, the gain of the circuit is 1 + R2/R1, which is

approximately 100. Tighter matching of two op amps in one

package, like the AD8622, offers a significant boost in

Figure 52. Input Protection

PHASE REVERSAL

An undesired phenomenon, phase reversal (also known as

phase inversion) occurs in many op amps when one or both of

the inputs are driven beyond the specified input voltage range

(IVR), in effect reversing the polarity of the output. In some

cases, phase reversal can induce lockups and even cause

equipment damage as well as self destruction.

performance over the classical 3-op-amp configuration. Overall,

The AD8622 amplifiers have been carefully designed to prevent

output phase reversal when both inputs are maintained within

the specified input voltage range. In addition, even if one or

both inputs exceed the input voltage range but remain within

the supply rails, the output still does not phase reverse. Figure 53

shows the input/output waveforms of the AD8622 configured as a

unity-gain buffer with a supply voltage of 15 V.

the circuit only requires about 430 μA of supply current.

AD8622

The ADR121 is a precision micropower 2.5 V voltage reference.

A precision voltage reference is required to hold a constant current

so that the Hall voltage only depends on the intensity of the mag-

netic field. Using the 4.12k:98.8k resistive divider, the bias

voltage of the Hall element is reduced to 100 mV, leading to only

250 μA of power consumption. The 3-op-amp in-amp

configuration of the AD8622 then increases the sensitivity to

55 mV/mT. Using the AD8622 to amplify the sensor signal can

reduce power while also achieving higher sensitivity. The total

current consumed is just 1.2 mA, resulting in 21× improvement in

sensitivity/power.

HALL SENSOR SIGNAL CONDITIONING

The AD8622 is also highly suitable for high accuracy, low power

signal conditioning circuits. One such use is in Hall sensor

signal conditioning (see Figure 55). The magnetic sensitivity of

a Hall element is proportional to the bias voltage applied across

it. With 1 V bias voltage, the Hall element consumes about

2.5 mA of supply current and has a sensitivity of 5.5 mV/mT

typical. To reduce power consumption, bias voltage must be

reduced, but at the risk of lower sensitivity. The only way to

achieve higher sensitivity is by introducing a gain using a

precision micropower amplifier. The AD8622, with all its

features, is well suited to amplify the sensitivity of the Hall

element.
