Product details
Overview
5962-87591053A from Analog Devices is a military-grade, monolithic silicon 12-bit analog-to-digital converter with 5 µs conversion time, 11-bit linearity, and 25 ppm/°C internal voltage reference drift. It operates from dual supplies (VDD = +4.75 to +5.25 V, VSS = –14.25 to –15.75 V) across –55°C to +125°C and interfaces directly with TTL/CMOS logic in slow memory or ROM modes. It is used in precision data acquisition systems for avionics and missile guidance where high reliability under extreme temperature and radiation-hardened environments is required.
For engineers reviewing the 5962-87591053A datasheet, 5962-87591053A pinout, 5962-87591053A application, or 5962-87591053A equivalent, this part supports parallel 12-bit output with asynchronous/synchronous clocking, features ±1 LSB differential linearity over full temperature range, and delivers guaranteed performance per MIL-PRF-38535 Class B requirements - critical for defense system qualification and long-lifecycle embedded deployments.
Technical Context
This device implements a successive-approximation register (SAR) ADC architecture with on-chip 5.25 V internal reference and buffered analog input stage. It supports two operational modes: slow memory mode (0–5 V input range) and ROM mode, each with distinct timing diagrams for parallel read access and bus relinquish behavior.
It uses a 24-pin dual-in-line hermetic package (outline L), requires separate analog and digital ground planes (AGND/DGND), and features three control inputs (CS, RD, HBEN) plus BUSY status flag for handshaking. Clock input accepts either synchronous (1.0 MHz or 2.5 MHz depending on variant) or asynchronous operation, with conversion time tightly specified at 4.8–5.2 µs for device type 05.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - provides 4096 discrete output codes for high-fidelity signal digitization. |
| Conversion Time | 5 µs (synchronous) / 4.8–5.2 µs (asynchronous) - enables ≥200 kSPS sampling in real-time control loops. |

| Differential Linearity Error | ±1 LSB - guarantees no missing codes and accurate small-signal step response. |
| Reference Drift | 25 ppm/°C - maintains <±0.03% full-scale error over –55°C to +125°C without external calibration. |
| Supply Range | VDD = +4.75 to +5.25 V, VSS = –14.25 to –15.75 V - compatible with standard ±15 V analog subsystems with margin for rail tolerance. |
| Operating Temperature | –55°C to +125°C - qualified for airborne, space, and ground vehicle mission-critical electronics. |

Pinout & Package
5962-87591053A is supplied in a 24-pin hermetic dual-in-line package (MIL-STD-1835 outline L, GDIP3-T24), with gold-plated leads and glass-sealed ceramic body rated for military environmental stress screening.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (AIN) | Analog Input | Single-ended input accepting 0 to +5.0 V dc; internally referenced to AGND; max ±15 V absolute rating. |
| 2 (VREF) | Internal Reference Output | –5.25 V nominal output; sinks up to 550 µA; used to bias external circuitry or calibrate gain stages. |
| 3 (AGND) | Analog Ground | Separate ground return for analog section; must be isolated from DGND to minimize noise coupling. |
| 4–16 (D11–D0/8) | Parallel Data Outputs | 12-bit bidirectional data bus (D11–D0); D0/8 through D3/11 are multiplexed for 8-bit interface mode when HBEN active. |
| 12 (DGND) | Digital Ground | Dedicated ground for digital I/O; connects to system logic ground; separation from AGND prevents digital switching noise from corrupting conversion. |
| 17 (CLK IN) | Master Clock Input | Accepts TTL/CMOS-compatible clock; 2.5 MHz max for device type 05; defines conversion timing resolution. |
| 18 (CLK OUT) | Clock Output | Buffered inverted copy of CLK IN; used to synchronize external latch or FIFO timing. |
| 19 (HBEN) | High-Byte Enable | Activates 8-bit mode: outputs D11–D4 on D3/11–D0/8 pins during second RD cycle; reduces bus width requirement. |
| 20 (RD) | Read Strobe | Active-low control initiating data transfer; triggers bus relinquish timing (t7) and defines data access window (t3). |
| 21 (CS) | Chip Select | Active-low enable; must be asserted before RD; controls CS-to-RD setup (t1 = 0 ns) and hold (t5 = 0 ns) timing. |
| 22 (BUSY) | Status Flag | Active-high open-collector output indicating conversion in progress; used for polling or interrupt-driven read sequencing. |
| 23 (VSS) | Negative Supply | –15 V nominal analog supply rail; powers internal reference and analog front-end; absolute max –17 V. |
| 24 (VDD) | Positive Supply | +5 V nominal digital/analog supply; powers logic core, reference buffer, and output drivers; absolute max +7 V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7572TQ05/883B | Same die, identical electrical specs, but packaged in 24-pin CERDIP (outline T) instead of GDIP3-T24; lead finish and screening level match 5962-87591053A. | Compatible in same PCB footprint only if outline T pad layout is used; not pin-compatible with GDIP3-T24 due to different lead pitch and body dimensions. | Select when CERDIP packaging is mandated by program-level form-fit requirements or legacy board compatibility. |
| MX7572SE05/883B | Functionally equivalent 12-bit SAR ADC with 5 µs conversion, but reference drift is 45 ppm/°C (not 25 ppm/°C); tested to same MIL-PRF-38535 Class B flow. | Acceptable where tighter reference stability is not required; may necessitate additional system-level calibration for high-accuracy metrology applications. | Choose for cost-sensitive programs where ±0.05% full-scale drift over temperature is acceptable and Maxim's QML-38535 sourcing is preferred. |
Compared with AD7572TQ05/883B, 5962-87591053A offers GDIP3-T24 packaging optimized for high-vibration environments; compared with MX7572SE05/883B, it delivers superior reference stability critical for uncalibrated long-duration missions - making 5962-87591053A the preferred choice for flight-critical and strategic defense systems.

FAQ
What is the maximum clock frequency supported by 5962-87591053A?
The 5962-87591053A supports a maximum clock frequency of 2.5 MHz, as specified for device types 04–06 in the drawing. This enables its 5 µs conversion time in synchronous mode. Exceeding 2.5 MHz violates timing specifications and may cause conversion errors or BUSY flag misalignment. The part is not characterized for operation beyond this limit, even at room temperature.
Does 5962-87591053A require an external reference voltage?
No, 5962-87591053A does not require an external reference voltage. It integrates a precision –5.25 V internal reference (VREF pin) with 25 ppm/°C temperature coefficient, fully characterized over –55°C to +125°C. The reference is used internally for analog-to-digital conversion and can also sink up to 550 µA for external biasing, eliminating the need for external reference components in most applications.
What is the meaning of "device type 05" in the 5962-87591053A part number?
In the 5962-87591053A designation, "05" is the device type code specifying a 5 µs conversion time, 11-bit linearity, and 25 ppm/°C reference drift configuration of the AD7572 core. This distinguishes it from other variants like 01 (12.5 µs, 45 ppm/°C) or 06 (5 µs, 12-bit linearity). All electrical and timing parameters for 5962-87591053A are defined under device type 05 in Table I of the drawing.
Can 5962-87591053A operate with a single +5 V supply?
No, 5962-87591053A cannot operate with a single +5 V supply. It requires dual supplies: VDD = +4.75 to +5.25 V and VSS = –14.25 to –15.75 V. The negative supply powers the internal reference and analog input stage. Attempting single-supply operation violates absolute maximum ratings (VSS to DGND = +0.3 V to –17 V) and will result in functional failure or permanent damage.
Is 5962-87591053A pin-compatible with commercial AD7572 variants?
No, 5962-87591053A is not pin-compatible with commercial AD7572 variants such as AD7572JN or AD7572KN. While sharing the same core functionality, 5962-87591053A uses a 24-pin GDIP3-T24 hermetic package per MIL-STD-1835 outline L, whereas commercial versions use plastic DIP or SOIC packages with different pinouts, lead finishes, and thermal characteristics. PCB layout must be designed specifically for the GDIP3-T24 footprint.
