LTC2204IUK#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2204IUK#TRPBF is a 16-bit, 40Msps sampling analog-to-digital converter (ADC) from Analog Devices. It features an internal programmable gain amplifier (PGA) allowing selectable input ranges of 1.5Vp-p or 2.25Vp-p. The device delivers high dynamic performance with a typical signal-to-noise ratio (SNR) of 79dB and spurious-free dynamic range (SFDR) of 100dB at low frequencies. Key specifications include a 700MHz full-power bandwidth, 90fs RMS aperture jitter, and ±4LSB maximum integral nonlinearity error. It operates on a single 3.3V supply with power dissipation of 480mW at the specified sample rate.

Analog To Digital Converters (ADC) Feature Summary

• 16-Bit Resolution: Provides no missing codes with ±4LSB max INL and ±1LSB max DNL over temperature.
• High Dynamic Performance: Achieves 79dB SNR and 100dB SFDR with a 700MHz full-power bandwidth.
• Integrated PGA Front End: Allows optimization of the input range to either 1.5Vp-p or 2.25Vp-p via the PGA pin.
• Low Jitter Sampling: Features ultralow 90fs RMS aperture jitter for excellent noise performance in undersampling applications.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix #TRPBF confirms the component is supplied in tape and reel packaging. Confirm the I suffix indicates an industrial temperature range of –40°C to 85°C. Ensure the source documentation matches the manufacturer's official datasheet for the LTC2205/LTC2204 family to validate these specific electrical parameters.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2204IUK#TRPBF when a 40Msps sampling rate is sufficient for the application, as opposed to the faster LTC2205 variants. The 'I' grade is required for operations below 0°C. The '#TRPBF' suffix denotes lead-free finish and tape-and-reel shipping format. Verify compatibility with the 48-lead QFN footprint during PCB layout.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2205/LTC2204 family of 16-bit ADCs. The LTC2204 is the 40Msps variant within this series, while the LTC2205 offers 65Msps. Both share identical pinouts and architectural features, including the PGA and digital interfaces. The family also includes 14-bit versions such as the LTC2205-14.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same package include the LTC2205 (65Msps), LTC2206 (80Msps), and LTC2207 (105Msps). Lower speed options like the LTC2201 (20Msps) are available but require verification of interface compatibility.
