LTC2356CMSE-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2356CMSE-12#TRPBF is a 12-bit, 3.5Msps serial sampling analog-to-digital converter (ADC) from Analog Devices Inc., housed in a 10-lead MSOP package. It operates on a single 3.3V supply, drawing 5.5mA during active conversion and reducing power to 4µA in Sleep mode. The device features differential inputs with a ±1.25V bipolar range, an internal 2.5V bandgap reference, and a 3-wire SPI-compatible interface. Key performance metrics include 71.1dB SINAD at 12-bit resolution, 80dB common-mode rejection, and 18mW power dissipation.

Analog To Digital Converters (ADC) Feature Summary

• Differential analog inputs supporting ±1.25V bipolar signal range
• Integrated 2.5V internal bandgap reference with overdrive capability
• Low power consumption: 18mW active, 13µW in Sleep mode

Analog To Digital Converters (ADC) Applications

• Portable data acquisition systems
• Multiphase motor control
• RFID readers
• Uninterrupted power supplies

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the order quantity aligns with standard reel sizes specified by the manufacturer.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of high speed and low power is required in a compact footprint. The 12-bit resolution suits applications needing moderate precision without the overhead of higher bit counts. Verify that the system clock supports the required 3.5Msps throughput and that the input signal amplitude fits within the ±1.25V differential range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2356 family, which also includes the 14-bit LTC2356-14 variant. Both share identical pinouts, interfaces, and power characteristics, differing primarily in resolution and associated dynamic performance specifications such as SINAD and noise levels.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same package and specification profile are limited. The LTC2356CMSE-14#TRPBF offers higher resolution but maintains compatibility. Cross-family replacements require verification of pinout, voltage levels, and interface timing.
