Product details
Overview
5962-0051101NXD from Texas Instruments is a military-grade 14-bit, 1 MSPS analog-to-digital converter (ADC) with differential inputs, internal 2-V reference (REF+ = 2.5 V, REF− = 0.5 V), programmable gain amplifier (0–7 dB), and µP-compatible parallel interface. It operates from a single 3.3-V supply, supports −55°C to +125°C temperature range, and targets high-reliability xDSL front ends and instrumentation systems requiring precision timing and low distortion.
For engineers reviewing the 5962-0051101NXD datasheet, 5962-0051101NXD pinout, 5962-0051101NXD application, or 5962-0051101NXD equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The 5962-0051101NXD implements a pipeline ADC architecture with 9.5-cycle latency and supports straight binary or 2's complement output format via control register bit D11. Its on-chip PGA provides digitally programmable gain in 1-dB steps (0–7 dB), with ±0.25 dB gain error and independent offset correction register (±128 LSB range).
It features fully differential analog input (IN+, IN−) accepting ±2 V differential full-scale range referenced to internal ∆REF = 2 V, and includes dedicated OV (out-of-range) flag output synchronized to pipeline delay. Digital I/O uses 3-state buffers controlled by OE, compatible with 3.3-V CMOS logic and timing-locked to TMS320C6000 DSP interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - delivers 16,384 discrete output codes for high dynamic range signal digitization. |
| Sampling Rate | 1 MSPS - supports Nyquist-limited bandwidth up to 500 kHz with adequate anti-aliasing filtering. |
| DNL / INL | ±0.6 / ±1.5 LSB typ - ensures monotonicity and minimal code-width deviation critical for closed-loop control accuracy. |
| ENOB | 11.2–11.5 bits - reflects effective resolution after quantization noise and harmonic distortion at 100 kHz input. |
| Power Consumption | 270–360 mW at 3.3 V - enables integration into thermally constrained military avionics and radar subsystems. |
| Operating Temperature | −55°C to +125°C - qualified per MIL-PRF-38535 for extended life in harsh environmental deployments. |
| Analog Input Bandwidth | 140 MHz - allows direct sampling of IF signals without external amplification in communications receivers. |
Pinout & Package
5962-0051101NXD is housed in a 48-pin HTQFP (PHP) package with exposed thermal pad, JEDEC MS-026 compliant, moisture sensitivity level 3 (260°C peak reflow, 168-hour floor life).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN− | Differential analog input pair | Accepts ±2 V differential signal; common-mode voltage set by CML pin; requires matched 22-Ω series termination and 100-pF AC coupling for optimal SFDR. |
| REF+, REF− | Reference voltage outputs | Provide fixed 2.5 V / 0.5 V rails (ΔREF = 2 V); each requires 0.1-µF decoupling to AGND for stable conversion accuracy. |
| VBG | Bandgap reference input | Accepts external 1.5-V reference; bypassed with 1-µF capacitor to AGND; internal reference disabled when D12 = 1 in control register. |
| D[13:0], OV | Parallel data bus + out-of-range flag | 14-bit conversion result plus 1-bit OV status; all outputs 3-state controlled by OE; pipeline latency = 9.5 clocks. |
| CLK, CS, WR, OE, A[1:0] | Digital control interface | µP-compatible timing; A[1:0] selects register readback (0=ADC result, 1=PGA, 2=offset, 3=control); WR active-low writes to PGA/offset/control registers. |
| AGND, DGND, AVDD, DVDD | Analog/digital power and ground | Separate analog/digital supplies and grounds required; multiple pins per rail reduce IR drop and improve PSRR above 100 kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Gain Amplifier (0–7 dB) | Enables single ADC to handle variable input signal amplitudes without external gain stages-reducing BOM count and layout area in multi-channel sensor interfaces. |
| Internal 2-V Reference (REF+/REF−) | Eliminates need for external precision reference IC and associated passive components-simplifying calibration and improving long-term dc stability over temperature. |
| Out-of-Range (OV) Flag Output | Provides immediate hardware-level saturation detection synchronized to data output-enabling real-time clipping mitigation in digital signal processors without software polling overhead. |
| Offset Correction Register (±128 LSB) | Allows system-level offset trimming of front-end amplifiers and filters-improving absolute accuracy in closed-loop industrial control applications without manual potentiometer adjustment. |
| TMS320C6000 Timing Compatibility | Matches TI DSP parallel interface timing directly-removing need for glue logic or FIFO buffering in radar and comms baseband processing modules. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed precision ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS1401IPFB | Same core architecture, 1 MSPS, but commercial/industrial grade (−40°C to +85°C), TQFP-48 package, no MIL-spec screening. | Lacks radiation tolerance, burn-in, and extended temperature validation; unsuitable for flight-critical or sealed-housing military deployments. | Select THS1401IPFB only for cost-sensitive industrial control or lab instrumentation where military qualification is not mandated. |
| ADS8364IPF | 16-bit, 250 kSPS SAR ADC; lower speed but higher resolution; external reference required; SPI interface instead of parallel. | Better dc accuracy (±1 LSB INL) but insufficient throughput for real-time IF sampling; incompatible timing and bus protocol with existing C6000-based designs. | Choose ADS8364IPF when absolute dc precision outweighs speed-e.g., precision DC motor current sensing-not for dynamic waveform capture. |
Compared with THS1401IPFB, 5962-0051101NXD adds MIL-PRF-38535 Class K screening, extended temperature operation, and enhanced reliability testing-justifying its use in mission-critical systems where field failure is unacceptable. Compared with ADS8364IPF, it trades resolution for speed and parallel interface compatibility, enabling direct integration into legacy DSP-based signal chains without firmware or PCB redesign.

FAQ
What is the maximum clock frequency supported by the 5962-0051101NXD?
The 5962-0051101NXD supports a maximum clock frequency of 1 MHz, as specified for the THS1401 speed grade. This is confirmed in the Recommended Operating Conditions table (page 4) and Electrical Characteristics (page 5), where fCLK max = 1 MHz applies to C- and I-suffix devices-and the 5962-0051101NXD is the military variant of THS1401. Exceeding this frequency risks timing violations and invalid conversion results.
Does the 5962-0051101NXD include an internal voltage reference?
Yes, the 5962-0051101NXD includes an internal bandgap reference generating REF+ = 2.5 V and REF− = 0.5 V (ΔREF = 2 V), with ±5% accuracy and 40 ppm/°C temperature coefficient. This reference can be disabled via D12 in the control register to allow external reference substitution-confirmed in the "Internal/External Reference Operation" section (page 19) and Electrical Characteristics (page 6).
How is the programmable gain amplifier (PGA) configured on the 5962-0051101NXD?
The PGA on the 5962-0051101NXD is configured by writing a 3-bit value (G2–G0) to address 1 (PGA register) via the parallel interface. Gain = 1 dB × G2–G0, spanning 0–7 dB in 1-dB steps, with ±0.25 dB gain error. Default state is 0 dB (all bits zero), and configuration occurs synchronously with WR pulse-detailed in Table 2 (page 15) and "Programmable Gain Amplifier" section (page 19).
What does the OV (out-of-range) pin indicate on the 5962-0051101NXD?
The OV pin on the 5962-0051101NXD asserts high when the differential analog input (IN+ − IN−) exceeds ±2 V (i.e., |ΔAIN| > ΔREF). It updates with the same 9.5-cycle pipeline latency as the digital output data, providing hardware-level saturation detection without software polling-described in the "Out of Range Indication" section (page 19) and Terminal Functions table (page 2).
Is the 5962-0051101NXD pin-compatible with other THS140x variants?
Yes, the 5962-0051101NXD shares identical pinout and package footprint (HTQFP-48 PHP) with THS1401IPFB (TQFP-48 PFB), THS1403IPFB, and THS1408IPFB per the "Available Options" table (page 3) and Package Option Addendum. However, electrical timing and thermal characteristics differ due to package construction (PHP vs. PFB), requiring validation of power delivery and signal integrity in new layouts.
