Product details
Overview
5962-8876402LX from Analog Devices is a military-grade, 8-channel, 8-bit analog-to-digital converter (ADC) fabricated in LC2MOS technology, operating from a single 5 V supply with ±1/2 LSB total unadjusted error, 2.5 µs conversion time per channel, and built-in track-and-hold for 10 kHz full-scale signal handling - used in real-time speech analysis and multichannel data acquisition systems.
For engineers reviewing the 5962-8876402LX datasheet, 5962-8876402LX pinout, 5962-8876402LX application, or 5962-8876402LX equivalent, this page delivers verified technical context, military-spec timing and accuracy parameters, DIP-28 package layout, microprocessor interface guidance for Z80/MC68000/TMS32010, and validated alternatives for radiation-tolerant embedded control designs.
Technical Context
The 5962-8876402LX implements a half-flash architecture using two 4-bit flash ADCs - one for MSBs and one for LSBs - with an internal 4-bit DAC to reconstruct and subtract the MSB-derived analog value before LSB conversion. This eliminates external clock requirements and enables deterministic 2.5 µs conversion time.
It features fully differential reference inputs (VREF(+) and VREF(–)), allowing ratiometric operation and offset-adjustable unipolar (0 V to 5 V) or bipolar (±4 V) input ranges. Its analog input structure inherently performs sample-and-hold over ~1 µs, supporting direct digitization of 10 kHz signals without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - delivers 256 discrete digital codes across full-scale range. |
| Total Unadjusted Error | ±1/2 LSB max - ensures monotonicity and no missing codes without user calibration. |
| Conversion Time | 2.5 µs per channel (Mode 0) - enables 100 kHz per-channel sampling on AD7824-compatible variants and 50 kHz on 8-channel operation. |
| Analog Input Bandwidth | 10 kHz full-scale - supports direct digitization of sinusoidal signals up to 157 mV/µs slew rate without external sample-and-hold. |
| Supply Voltage | 5 V ±5% - simplifies system power design with single-rail operation and 50 mW typical power dissipation. |
| Operating Temperature | –55°C to +125°C - qualified to MIL-STD-883 Class B for extended military and aerospace environments. |
| Digital Interface | CS/RD-controlled, WAIT-state compatible - interfaces directly as memory-mapped peripheral to Z80, MC68000, and TMS32010 without glue logic. |
Pinout & Package
5962-8876402LX is supplied in a 28-lead plastic dual-in-line package (PDIP, N-28), 0.6" wide, compliant with JEDEC MS-011AB. Pin 1 identifier located at top-left corner when viewed from top with notch or dot oriented upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN1–AIN8 | Analog input channels | Eight single-ended inputs selectable via A0/A1/A2 address lines; support 0 V to 5 V unipolar or ±4 V bipolar operation with external op-amp conditioning. |
| A0, A1, A2 | Multiplexer address inputs | Binary-encoded channel selection (A2 only active on AD7828 family); latched on rising edge of RD in Mode 1. |
| CS | Chip Select | Active-low enable initiating conversion and enabling three-state outputs; controls RDY/INT assertion timing. |
| RD | Read strobe | Active-low signal that, with CS, triggers conversion (Mode 0) or reads prior result (Mode 1); defines data access window. |
| RDY | Ready status output | Open-drain, active-low signal indicating conversion completion; used to drive µP WAIT input in Mode 0. |
| INT | Interrupt output | Active-low pulse signaling end of conversion; returns high on rising edge of CS or RD. |
| DB0–DB7 | Three-state data bus | 8-bit parallel output delivering natural binary code; high-impedance when CS or RD is high. |
| VREF(+), VREF(–) | Differential reference inputs | Define zero-to-full-scale span; support ratiometric measurement and input offset (e.g., VREF(–) = 2.5 V yields 0–2.5 V range). |
| VDD, GND | Power supply | Single 5 V supply with decoupling recommended; GND serves as analog and digital common reference point. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-channel, 8-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7828CQ | Commercial-grade (–40°C to +85°C), same pinout and timing but lacks MIL-STD-883 screening and extended temp validation. | Not suitable for space, missile, or airborne platforms requiring radiation tolerance or extended temperature compliance. | Select AD7828CQ only for ground-based industrial systems where cost sensitivity outweighs environmental robustness requirements. |
| MAX195BCPP | 5 V, 16-bit, serial-output ADC with 1.2 µs conversion; no built-in MUX or track-and-hold; requires external clock and reference. | Higher resolution but adds complexity: needs external S/H, clock generator, and SPI interface logic - increases BOM count and layout area. | Choose MAX195BCPP only when 16-bit resolution is mandatory and system can accommodate added component count and timing coordination overhead. |
Compared with AD7828CQ, 5962-8876402LX provides guaranteed operation at –55°C and radiation-hardened reliability, while MAX195BCPP trades channel integration and simplicity for resolution - making 5962-8876402LX optimal for compact, deterministic, high-reliability 8-channel acquisition where 8-bit precision suffices.

FAQ
What is the operating temperature range specified for the 5962-8876402LX?
The 5962-8876402LX is qualified to operate from –55°C to +125°C per MIL-STD-883 Class B requirements. This extended range is validated through temperature cycling, burn-in, and parametric testing across the full interval - ensuring reliable performance in missile guidance systems, satellite power controllers, and jet engine monitoring units where ambient extremes are routine.
Does the 5962-8876402LX require an external clock signal for conversion?
No, the 5962-8876402LX does not require an external clock signal. Its half-flash architecture uses internal timing controlled solely by CS and RD strobes. Conversion begins on the falling edge of CS (with RD low in Mode 0), and completes deterministically in 2.5 µs - eliminating clock distribution, jitter concerns, and associated layout complexity in noise-sensitive military platforms.
How is the 5962-8876402LX interfaced to a Z80 microprocessor?
The 5962-8876402LX interfaces to the Z80 in Mode 0: CS and RD are connected to MREQ and RD, respectively, with RDY driving the WAIT input. When a memory read (e.g., LD B,(C000)) targets the ADC's address block, RDY holds the Z80 in WAIT until conversion completes and places the 8-bit result on DB0–DB7 - enabling seamless, cycle-accurate acquisition without software polling or additional wait-state logic.
Can the 5962-8876402LX perform bipolar input measurements?
Yes, the 5962-8876402LX supports bipolar operation via external signal conditioning. Using an AD544 op amp configured as shown in Figure 12, the analog input range becomes ±4 V with complementary offset binary output coding. The differential reference inputs (VREF(+) and VREF(–)) allow precise offset setting - enabling direct digitization of AC-coupled sensor outputs such as accelerometers or current-sense amplifiers in flight control surfaces.
What is the maximum analog input slew rate supported by the 5962-8876402LX?
The 5962-8876402LX supports analog input slew rates up to 157 mV/µs while maintaining ±1/2 LSB total unadjusted error. This corresponds to full-scale 10 kHz sinusoidal signals (5 V p-p), verified in TPC 3 of the datasheet. The inherent track-and-hold action over ~1 µs after conversion start ensures accurate capture without external sample-and-hold circuitry - critical for radar pulse detection and vibration monitoring in rotating machinery.
