ALD1103PBL

Overview

The ALD1103PBL is a monolithic dual N-channel and dual P-channel matched MOSFET pair housed in a 14-pin Plastic DIP package. It features a low threshold voltage of 0.7V, low input capacitance of 610pF, and an offset voltage of 10mV. The device operates within a +2V to +10V supply range with a maximum drain-source voltage of 10V. Thermal tracking between pairs ensures minimal differential thermal response, while high input impedance and negative current temperature coefficient support precision analog applications.

Feature Summary

• Monolithic integration of matched N-channel and P-channel enhancement-mode MOSFETs
• Thermal tracking between transistor pairs for stable differential performance
• Low threshold voltage and low input capacitance for fast switching
• High DC current gain with extremely low gate leakage currents

Applications

• Precision current mirrors and matched current sources
• Complementary push-pull linear drives
• Analog switches and choppers
• Differential amplifier input stages
• Sample and Hold circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and compliance status. Confirm that the component meets RoHS requirements if applicable to the design. Ensure static control procedures are utilized during handling due to ESD sensitivity. Validate operating temperature ranges align with system specifications before procurement.

Selection Notes

Select this component for applications requiring high input impedance and low offset voltage in low-voltage systems. Consider the 10V absolute maximum ratings when designing power supplies. Evaluate the negative current temperature coefficient for thermal stability requirements. Ensure the chosen package variant matches the PCB layout constraints.

Part Context

The ALD1103 belongs to a family of matched MOSFET pairs manufactured using ACMOS silicon gate CMOS process. It combines the functions of the ALD1101 N-channel pair and ALD1102 P-channel pair into a single package. This integration facilitates compact designs for analog signal processing and switching applications.

Replacement Considerations

Direct replacements include the ALD1101SBL or ALD1102SBL if only one channel type is required. Verify pin compatibility and electrical characteristics such as threshold voltage and on-resistance when substituting with other matched MOSFET pairs from different manufacturers.
