LTC2236CUH#PBF

Analog To Digital Converters (ADC) Overview

The Analog Devices LTC2236CUH#PBF is a 10-bit, 25Msps low-power analog-to-digital converter (ADC) housed in a 32-lead QFN package. It operates on a single 3V supply with typical power dissipation of 75mW. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 61.8dB and a Spurious Free Dynamic Range (SFDR) of 85dB at the Nyquist frequency. The device features flexible input ranges selectable between ±0.5V and ±1V via the SENSE pin, an internal reference, and supports both offset binary and two's complement output formats.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade suffix when ordering; 'C' indicates commercial range (0°C to 70°C), while 'I' denotes industrial range (-40°C to 85°C). Confirm that the #PBF suffix corresponds to lead-free packaging standards. Ensure the selected variant matches the required operating environment before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2236CUH#PBF for applications requiring a 25Msps sampling rate with 10-bit resolution. Use this part instead of the LTC2238 or LTC2237 if lower bandwidth and reduced power consumption are prioritized over higher sample rates. Ensure the design accommodates the 32-pin QFN footprint and provides adequate thermal management for the exposed pad.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC223x family of low-noise 3V ADCs, which also includes the LTC2238 (65Msps) and LTC2237 (40Msps). All members share identical pinouts and functional blocks, allowing for direct pin-compatible upgrades or downgrades within designs based on bandwidth requirements.

Analog To Digital Converters (ADC) Replacement Considerations

For equivalent performance, consider the LTC2237 (40Msps) or LTC2238 (65Msps) as they are pin-compatible. Verify that the system clock and input drive capabilities support the higher sampling rates if upgrading.
