TC9400COD713

Overview

The TC9400COD713 is a Voltage-to-Frequency and Frequency-to-Voltage converter manufactured by Microchip Technology. It utilizes low-power CMOS technology to provide linear conversion between analog voltage signals and digital pulse trains. The device supports operation from DC to 100 kHz in F/V mode and 1 Hz to 100 kHz in V/F mode. It features a linearity of 0.05% at full scale, with a gain temperature stability of ±25 ppm/°C typical. The component operates on single or dual supplies ranging from +8V to +15V or ±4V to ±7.5V. It is housed in a 14-pin SOIC package.

Feature Summary

• Provides bidirectional conversion between voltage and frequency domains using charge balancing techniques.
• Features programmable scale factors for flexible system integration.
• Includes open-drain outputs compatible with MOS, CMOS, and TTL logic families.
• Operates with low power dissipation suitable for battery-powered applications.

Applications

• Microprocessor data acquisition systems
• Analog data transmission and recording
• Phase locked loops
• Frequency meters and tachometers
• Motor control circuits

Procurement Notes

Verify the specific suffix '713' indicates tape and reel packaging when ordering. Confirm the 'C' designation aligns with the required commercial operating temperature range of 0°C to +70°C. Ensure the 14-SOIC footprint matches the target PCB layout. Check for RoHS compliance status as per current manufacturer declarations.

Selection Notes

Select this component for applications requiring high linearity and low power consumption. Consider the TC9401 if tighter linearity specifications are necessary. Evaluate the external component requirements for capacitors and resistors to achieve desired frequency ranges. Verify supply voltage compatibility with the system architecture before implementation.

Part Context

This part belongs to the TC9400 family of precision converters. It shares functional similarities with the TC9401 and TC9402, differing primarily in linearity accuracy. The TC9400 offers a balanced performance profile for general-purpose conversion tasks. It serves as a bridge between analog sensors and digital processing units.

Replacement Considerations

The TC9400EOD is a direct replacement offering an extended industrial temperature range. The TC9400CPD provides a through-hole alternative for legacy board designs. Verify pinout compatibility and thermal characteristics when substituting these variants.
