NXP Semiconductors ADC1412D125HN/C1:5

Overview

ADC1412D125HN/C1 from NXP Semiconductors is a dual-channel, 14-bit pipelined analog-to-digital converter optimized for high dynamic performance and low power at 125 Msps sample rate. It delivers 72.1 dBFS SNR, 86 dBc SFDR, and 600 MHz input bandwidth, with zero missing codes guaranteed across full operating range. It supports both CMOS and LVDS DDR digital outputs and operates from a single 3 V analog supply, serving as a front-end digitizer in broadband communications and ultrasound systems.

For engineers reviewing the ADC1412D125HN/C1 datasheet, ADC1412D125HN/C1 pinout, ADC1412D125HN/C1 application, or ADC1412D125HN/C1 equivalent, key selection considerations include its dual-channel 14-bit resolution at 125 Msps, LVDS DDR/CMOS output flexibility, programmable 1–2 V_p-p input range, integrated SPI configuration interface, and HVQFN64 thermal-enhanced package for high-density RF signal chain designs.

Technical Context

The ADC1412D125HN/C1 employs a pipelined architecture with on-chip error correction to ensure monotonicity and zero missing codes. Its clock input stage includes a duty cycle stabilizer (DCS) and optional divide-by-2 function to reduce jitter sensitivity, supporting differential LVPECL or LVCMOS clock inputs up to 125 MHz.

Dual independent analog channels (A and B) accept differential inputs with common-mode voltage set to 0.5×VDDA (1.5 V typical), and feature fast Out-of-Range (OTR) detection per channel. Output data format (offset binary, two's complement, gray code) and output standard (CMOS/LVDS DDR) are configurable via SPI or pin-strapping.

FAQ

What is the maximum sample rate supported by the ADC1412D125HN/C1?

The ADC1412D125HN/C1 supports a maximum sample rate of 125 Msps, as indicated by the "125" in its part number. This rating is validated across the full industrial temperature range (−40 °C to +85 °C) and applies to both analog input channels simultaneously. At this rate, the device maintains 72.1 dBFS SNR at low input frequencies and >69.9 dBFS at 170 MHz, confirming sustained dynamic performance at full speed.

Does the ADC1412D125HN/C1 support LVDS DDR output mode?

Yes, the ADC1412D125HN/C1 fully supports LVDS DDR output mode, with dedicated differential pin pairs (e.g., DA0_DA1_P/M, DB12_DB13_P/M) and true/complement data valid clocks (DAVP/DAVM). LVDS DDR mode requires VDDO = 3.0 V and delivers lower EMI and reduced pin count versus CMOS, while maintaining 350 mV differential output swing and 100 Ω termination compatibility.

How is the full-scale input range configured on the ADC1412D125HN/C1?

The ADC1412D125HN/C1 supports a programmable full-scale input range of 1 V_p-p to 2 V_p-p via its integrated SPI-configurable reference. The setting is controlled through register bits in the SPI interface (Table 23 of datasheet), and does not require external components. This flexibility allows direct interfacing with diverse front-end amplifiers without additional scaling circuitry.

What power supply voltages are required for the ADC1412D125HN/C1?

The ADC1412D125HN/C1 requires two independent supplies: VDDA = 2.85–3.4 V (analog core, typical 3.0 V) and VDDO = 1.65–3.6 V (digital outputs). In CMOS mode, VDDO may be 1.8 V or 3.3 V; in LVDS DDR mode, VDDO must be 3.0 V. Separate AGND and DGND connections are recommended, with multiple AGND pins provided for low-impedance return paths.

Is the ADC1412D125HN/C1 pin-compatible with other devices in the ADC1212D or ADC1112D families?

Yes, the ADC1412D125HN/C1 is pin and software compatible with the ADC1212D series and ADC1112D125, as explicitly stated in the datasheet features list. This compatibility extends to identical HVQFN64 (SOT804-3) footprint, matching pin functions (e.g., INAP, CLKP, DA0–DA13), and shared SPI register map-enabling drop-in upgrades or migration paths within existing PCB layouts and firmware.
