NXP Semiconductors ADC1410S105HN/C1:5

Overview

ADC1410S105HN/C1 from NXP Semiconductors is a single-channel, 14-bit pipelined analog-to-digital converter optimized for high dynamic performance and low power at 105 Msps sample rate. It delivers 71.8 dBFS SNR and 85 dBc SFDR at 70 MHz input, supports both CMOS and LVDS DDR outputs, and operates from a single 3 V analog supply with flexible 1–2 V_p-p input range - ideal for ultrasound front-ends and broadband receiver digitization.

For engineers reviewing the ADC1410S105HN/C1 datasheet, ADC1410S105HN/C1 pinout, ADC1410S105HN/C1 application, or ADC1410S105HN/C1 equivalent, key selection factors include its 105 Msps throughput, HVQFN40 package thermal performance (R_th(j-a) = 22.5 K/W), SPI-configurable output standard/format, duty cycle stabilizer, and fast OTR detection for real-time signal integrity monitoring.

Technical Context

The ADC1410S105HN/C1 implements a 14-bit pipelined architecture with on-chip error correction to guarantee zero missing codes across temperature and supply variations. Its clock input stage includes a duty cycle stabilizer (DCS) and clock divider-by-2 functionality to reduce jitter sensitivity, enabling robust sampling up to 105 MHz fundamental clock frequency.

Dual-output interface support is implemented via pin-selectable or SPI-configurable modes: CMOS (14-bit parallel D13–D0 + DAV) or LVDS DDR (7 differential pairs D0_D1_P/M through D12_D13_P/M + DAVP/DAVM). The device integrates programmable full-scale reference control via SENSE/VREF pins or SPI, allowing precise 1–2 V_p-p input range tuning without external components.

FAQ

What is the maximum input frequency supported by the ADC1410S105HN/C1?

The ADC1410S105HN/C1 features a 600 MHz analog input bandwidth, enabling accurate digitization of signals up to 170 MHz while maintaining 70 dBFS SNR and 80 dBc SFDR. This supports undersampling architectures for IF digitization in wireless infrastructure and radar systems without requiring external bandpass filtering below 170 MHz.

Does the ADC1410S105HN/C1 support both CMOS and LVDS DDR output interfaces?

Yes, the ADC1410S105HN/C1 supports both CMOS and LVDS DDR digital outputs. Output standard selection is configurable via SPI register or pin ODS (LVDS DDR when HIGH). LVDS DDR mode uses 7 differential pairs to transmit 14 bits, reducing pin count and improving noise immunity compared to parallel CMOS.

How does the programmable input voltage range work on the ADC1410S105HN/C1?

The ADC1410S105HN/C1 allows full-scale input range adjustment from 1 V_p-p to 2 V_p-p using either the SENSE/VREF pins (analog programming) or SPI-controlled internal reference (INTREF[2:0]). This eliminates external gain stages when interfacing with variable-output sensors or mixers, preserving SNR across multiple signal levels.

What power-saving modes are available on the ADC1410S105HN/C1?

The ADC1410S105HN/C1 offers Power-down mode (14 mA total current) and Sleep mode (40 mA), both accessible via SPI or pin control (PWD/OE). Power-down halts conversion and disables outputs; Sleep retains configuration and reference bias while stopping sampling - enabling rapid wake-up (<76 μs) for burst-mode acquisition.

Is the ADC1410S105HN/C1 pin-compatible with other members of the ADC1410S family?

Yes, the ADC1410S105HN/C1 is pin-compatible with all ADC1410S variants (65/80/105/125 Msps) and also with the ADC1210S and ADC1010S series in HVQFN40 packaging. This enables drop-in upgrades or downgrades based on system-level speed, resolution, and power requirements without PCB redesign.
