ALD2736PAL

Overview

The ALD2736PAL is a precision dual ultra micropower CMOS operational amplifier manufactured by Advanced Linear Devices. It operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V, with all parameters specified at +5V single supply or ±2.5V dual supply. The device features rail-to-rail input and output voltage ranges, unity gain stability without external compensation, and extremely low input bias currents of 0.01pA typical. Key electrical characteristics include a bandwidth of 400KHz, a slew rate of 0.17V/µs, and a large signal voltage gain of 100V/mV. It is housed in an 8-pin Plastic DIP package.

Feature Summary

• Rail-to-rail input and output voltage ranges allow flexible signal biasing and serial stage implementation.
• Internally compensated for unity gain stability without requiring external frequency compensation components.
• Extremely low input bias current of 0.01pA typical, making it suitable for high source impedance applications.
• On-chip offset voltage trimming eliminates the need for nulling in most applications.

Applications

• Photodiode amplifiers
• Picoammeters
• Precision sample and hold amplifiers
• Voltage follower/buffer circuits

Procurement Notes

Verify that the ordering suffix 'PAL' corresponds to the 8-pin Plastic DIP package variant. Confirm the operating temperature range requirement matches the commercial grade specification (0°C to +70°C). Ensure static control procedures are followed during handling due to ESD sensitivity. Check if leaded versions are required, as the 'L' suffix denotes lead-free compliance.

Selection Notes

Select this component when designing low-power analog circuits powered by single or dual battery systems. It is appropriate for applications requiring high input impedance and rail-to-rail signal swing. Consider the 0.17V/µs slew rate and 400KHz bandwidth limits for signal processing requirements. Verify that the load conditions do not exceed the specified capacitive and resistive drive capabilities.

Part Context

This part belongs to the ALD2736A/ALD2736 family of precision dual ultra micropower CMOS operational amplifiers. The PAL suffix specifically identifies the 8-pin Plastic DIP package version intended for through-hole mounting. Other variants in the series include SOIC and CERDIP packages, offering different thermal and mechanical profiles for various PCB layouts.

Replacement Considerations

Direct substitutes within the same package and pinout configuration should be verified against the specific electrical parameters. Cross-referencing with other dual micropower op-amps requires checking rail-to-rail compatibility and input bias current specifications to ensure circuit performance retention.
