LTC2227IUH#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2227IUH#TRPBF is a 12-bit, 40Msps low power analog-to-digital converter (ADC) from Analog Devices. It operates on a single 3V supply and features a flexible input range of ±0.5V to ±1V. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 71.2dB and a Spurious Free Dynamic Range (SFDR) of 90dB at the Nyquist frequency. The device incorporates an internal reference, clock duty cycle stabilizer, and shutdown/nap modes for power management. It is housed in a 32-lead 5mm × 5mm QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #TRPBF indicates lead-free finish and tape and reel packaging. Confirm the 'I' grade designation corresponds to the –40°C to 85°C operating temperature range. Ensure compatibility with the 32-lead QFN footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2227 for applications requiring 40Msps throughput. Choose the 'I' variant for industrial temperature ranges. Use the SENSE pin configuration to set the input voltage range between ±0.5V and ±1V. Consider the OVDD supply for output driver logic level compatibility.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2226/LTC2227/LTC2228 family, differentiated by sampling rates of 25Msps, 40Msps, and 65Msps respectively. All members share pin compatibility and similar architectural features within the 12-bit low power 3V ADC category.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2226 (25Msps) and LTC2228 (65Msps). Higher speed options like the LTC2229 (80Msps) are also compatible but may require power budget adjustments.
