TC9400EOD

Overview

The TC9400EOD is a Voltage-to-Frequency and Frequency-to-Voltage converter manufactured by Microchip Technology. It operates within a supply voltage range of +8V to +15V or ±4V to ±7.5V, supporting full-scale frequencies up to 100 kHz. The device features an integral non-linearity of 0.05% and a gain temperature stability of ±25 ppm/°C. It utilizes low-power CMOS technology for efficient operation.

Feature Summary

• Utilizes charge balancing technique for high linearity
• Supports single or dual power supply configurations
• Features open-drain outputs compatible with standard logic families

Applications

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

Procurement Notes

Verify the 'E' suffix indicates the extended industrial temperature range (-40°C to +85°C) compared to the commercial variant. Confirm the 'OD' suffix corresponds to the 14-pin SOIC surface-mount package. Ensure compatibility with required supply voltages and reference impedance specifications before ordering.

Selection Notes

Select this component when precise V/F or F/V conversion is required with 0.05% linearity. Consider the operating temperature range and package type relative to the PCB layout constraints. Evaluate external component requirements for capacitors and resistors to achieve desired scale factors and frequency ranges.

Part Context

This part belongs to the TC9400 series of converters. It shares functional similarities with the TC9400CPD (commercial DIP) and TC9400COD (commercial SOIC), differing primarily in temperature rating and package style. The series offers variants with different linearity specifications such as the TC9401 and TC9402.
