ALD1704APAL

Overview

The ALD1704APAL is a CMOS monolithic operational amplifier featuring rail-to-rail input and output voltage ranges. It operates on dual supplies from ±3.25V to ±5.0V or single supplies up to 10.0V, consuming 30mW at ±5.0V. Key electrical parameters include a slew rate of 5.0V/µs, unity gain bandwidth of 2.1MHz, and typical input bias current of 1.0pA (max 20pA). The device offers large signal voltage gain of 150V/mV and settles to 0.1% in 2µs. It supports capacitive loads up to 4000pF at gain of 5 and includes short circuit protection.

Feature Summary

• Rail-to-rail input and output voltage ranges for extended dynamic range
• Extremely low input bias currents suitable for high source impedance applications
• High capacitive load driving capability without external compensation
• Symmetrical push-pull output stage with short circuit protection

Applications

• Voltage follower/buffer circuits
• Photodiode amplifiers
• Charge integrators
• Picoammeters
• Active filters

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package as defined in the ordering information. Confirm that the required operating temperature range aligns with the standard commercial grade (0°C to +70°C) rather than the industrial grade (-55°C to +125°C), which utilizes different suffixes such as 'DA'. Ensure static control procedures are followed due to ESD sensitivity.

Selection Notes

Select this component when low power consumption and rail-to-rail performance are required in an 8-pin DIP package. It serves as a direct alternative to JFET input amplifiers where lower operating voltages like 9V batteries or ±3.25V to ±5V supplies are used. Consider the 1.0pA typical input bias current for precision applications involving high-impedance sources.

Part Context

This device belongs to the ALD1704 family of rail-to-rail CMOS operational amplifiers manufactured by Advanced Linear Devices. The family includes variants ALD1704A, ALD1704B, ALD1704, and ALD1704G, differentiated primarily by offset voltage specifications and temperature ranges. The ALD1704APAL specifically denotes the standard commercial grade version housed in an 8-pin Plastic DIP package.

Replacement Considerations

Direct substitutes within the same family include ALD1704APAD (Industrial Grade) and ALD1704BPAL (Lower Offset Voltage). Verify package compatibility and temperature range requirements before substitution.
