LTM9012CY-AB#PBF

Analog To Digital Converters (ADC) Overview

The LTM9012CY-AB#PBF is a quad 14-bit, 125Msps analog-to-digital converter (ADC) housed in a 221-lead BGA package. It integrates fixed-gain differential drivers and lowpass filters for each channel. The device operates with a 1.8V ADC core supply and a 3.3V analog input supply. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 68.3dB and a Spurious Free Dynamic Range (SFDR) of 78dB at a 70MHz input frequency. Integral nonlinearity is typically ±1.2LSB, with no missing codes over the operating temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the CY suffix corresponds to the commercial temperature range of 0°C to 70°C. Ensure the AB variant matches the required pin configuration and package dimensions for the target PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring four synchronized high-speed channels with integrated signal conditioning. The internal reference and drivers simplify board design compared to discrete solutions. Consider the 221-lead BGA package size and thermal requirements when designing the heat dissipation strategy.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTM9012 family of µModule ADCs. The CY-AB designation specifies the commercial temperature grade and specific package/trim variant. Other variants include the I-grade version for industrial temperatures (-40°C to 85°C).

Analog To Digital Converters (ADC) Replacement Considerations

The LTM9012IY-AB#PBF serves as the industrial temperature grade replacement for the CY version. Verify that the temperature range requirements of the application align with the selected grade before substitution.
