ALD1701PAL

Overview

The ALD1701PAL is a monolithic CMOS micropower operational amplifier in an 8-pin PDIP package. It features rail-to-rail input and output voltage ranges, unity gain stability without external compensation, and extremely low input bias current of 1.0 pA typical (30 pA max). The device operates on dual supplies from ±1.0V to ±5.0V or single supply from +2.0V to +10.0V. Key electrical parameters include a unity gain bandwidth of 0.7 MHz, slew rate of 0.7 V/µs, and large signal voltage gain of 100 V/mV at ±2.5V. Operating temperature range is 0°C to +70°C.

Feature Summary

• Rail-to-rail input and output voltage capability for maximum dynamic range
• Extremely low input bias current suitable for high source impedance applications
• Internally compensated for unity gain stability with no frequency compensation required
• Output short circuit protection and robust design for rugged environments

Applications

• Voltage amplifier circuits
• Voltage follower/buffer configurations
• Charge integrator designs
• Photodiode amplifier interfaces
• Data acquisition systems

Procurement Notes

Verify the specific suffix PAL indicates the 8-pin Plastic DIP package and standard commercial temperature range. Confirm RoHS compliance status as leaded versions may be available upon request. Ensure the ordering code matches the exact variant (ALD1701 vs ALD1701G) required for your performance specifications. Check for any specific handling requirements due to ESD sensitivity.

Selection Notes

Select this component when low power consumption and high input impedance are critical. The rail-to-rail operation makes it suitable for single-supply battery-operated systems. Consider the 0.7 MHz bandwidth and 0.7 V/µs slew rate for moderate speed applications. Verify that the load requirements do not exceed the specified capacitive or resistive drive limits.

Part Context

The ALD1701 series includes variants like ALD1701A, ALD1701B, and ALD1701G, differentiated by offset voltage and drift specifications. The PAL suffix specifically denotes the 8-pin Plastic Dual In-Line Package. This family is designed for analog applications requiring trade-offs between performance and power dissipation.

Replacement Considerations
