LTC1407ACMSE-1#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1407ACMSE-1#TRPBF is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates on a single 3V supply and delivers a total sampling rate of 3Msps, with each channel providing 1.5Msps throughput via simultaneous sampling. The device features a 2.5V internal bandgap reference, a 3-wire serial interface, and differential inputs supporting ±1.25V swings. Key performance metrics include a full power bandwidth of 50MHz, 80dB common mode rejection at 100kHz, and low power consumption of 14mW in active mode. A sleep shutdown mode reduces power dissipation to 10μW.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel 14-bit SAR ADC with 3Msps total simultaneous sampling rate
• Low power operation: 14mW active, 10μW sleep mode
• Integrated 2.5V internal bandgap reference with external overdrive capability
• 80dB CMRR at 100kHz and 50MHz full power bandwidth

Analog To Digital Converters (ADC) Applications

• Telecommunications systems
• Data acquisition systems
• Multiphase motor control
• I & Q demodulation
• Industrial radio

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging for automated assembly. Confirm the 'A' grade designation indicates the commercial temperature range of 0°C to 70°C. Ensure compatibility with the 10-lead MSOP package footprint and exposed pad grounding requirements during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous dual-channel conversion is required at high speeds. The 14-bit resolution offers higher precision than the 12-bit LTC1407-1 variant. Consider the internal reference for simplified designs or use the VREF pin for external references exceeding 2.55V. Verify that the source impedance allows for the specified 39ns acquisition time without additional buffering.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1407-1/LTC1407A-1 family of serial ADCs. The 'A' suffix denotes the improved accuracy version with 14-bit resolution, while 'C' specifies the commercial temperature range. The 'MS' indicates the 10-lead plastic MSOP package, and '#TRPBF' signifies lead-free tape and reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC1407CMSE-1#TRPBF serves as a direct functional substitute but provides 12-bit resolution instead of 14-bit. Both share identical pinouts, power requirements, and package styles. Designers requiring higher precision must ensure the 14-bit specification of the LTC1407ACMSE-1#TRPBF is maintained.
