The pipelined architecture delivers the throughput needed for radar front-ends, motor-phase current sensing, and battery-monitoring systems where the input frequency can exceed several megahertz. The 1.14 V to 1.26 V analog and digital core supplies keep the power dissipation low enough that the 121-TFBGA package can be routed on a standard 4-layer automotive PCB without a dedicated heatsink. ## 80 MSPS sampling and the input bandwidth ceiling At 80 MSPS the Nyquist frequency is 40 MHz — the ADC can digitise input signals up to that fundamental without aliasing, though the effective resolution (ENOB) rolls off above a few megahertz due to the pipelined converter's aperture jitter and comparator ambiguity. For a 10 MHz input the ENOB typically stays above 10.5 bits; above 30 MHz the SNR drops enough that a higher-speed ADC or an external down-conversion stage may be warranted. The SPI data interface allows the conversion results to be read by a standard MCU or FPGA without a parallel bus — the serial clock rate must be at least 12× the sample rate to stream all 12 bits per channel before the next conversion completes. ## Active lifecycle and compliance posture No minimum order quantity is imposed beyond the tray packaging increment. ## Package and board-fit considerations The exposed centre pad (if present) should be connected to the analog ground plane with at least 9 thermal vias to keep the junction temperature below the 125°C limit under continuous 80 MSPS operation. The SPI lines should be kept under 50 mm trace length to avoid reflections at the 20 MHz+ serial clock rate needed to read out all channels. The differential input pair requires a 10 Ω to 50 Ω series resistor at the ADC input pin to damp the sampling glitch energy — the datasheet layout note will specify the exact value based on the source impedance. The internal MUX switches between channels in 1:1 S/H:ADC ratio, meaning the sample-and-hold captures the selected channel before conversion starts; channel-to-channel crosstalk is typically below -80 dB at 1 MHz.","metaTitle":"Microchip MCP37D11-80E/TE 12-bit 80 MSPS ADC, AEC-Q100","metaDescription":"Microchip MCP37D11-80E/TE pipelined ADC, 12-bit, 80 MSPS, 8-channel MUX, differential input, SPI, -40 to 125°C, 121-TFBGA.
