Product details
Overview
AD7575JNZ from Analog Devices is an 8-bit successive approximation analog-to-digital converter (ADC) with integrated track-and-hold, single +5 V supply operation, 5 µs conversion time, ±1 LSB total unadjusted error, and 0 to +70°C operating range. It digitizes full-scale signals up to 50 kHz (386 mV/µs slew rate) in microprocessor-based data acquisition systems.
For engineers reviewing the AD7575JNZ datasheet, AD7575JNZ pinout, AD7575JNZ application, or AD7575JNZ equivalent, key selection criteria include unipolar/bipolar input configuration support, internal/external clock flexibility, 18-pin DIP package compatibility, and direct interface to Z80, 8085A-2, 6502, and TMS32010 processors without external timing logic.
Technical Context
The AD7575JNZ implements a SAR architecture with on-chip track-and-hold that acquires input on the third falling edge of CLK after CS and RD assertion. Its LC2MOS process enables low power (15 mW typ) and fast digital interface timing - including 100 ns data access time and 100 ns RD pulse width minimum.
It supports two microprocessor interface modes: Slow Memory (WAIT-state driven via BUSY) and ROM-style (non-blocking, dual-read sequence). The TP pin must be hard-wired HIGH for functional operation and is reserved for factory test.
Key Specifications

Pinout & Package
AD7575JNZ is supplied in an 18-lead plastic DIP (N-18) package with 0.3" width and through-hole mounting. Pin 1 identifier is marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Digital supply | +5 V power for logic and output drivers; decoupling required near pin |
| AIN | Analog input | Single-ended unipolar (0–2.46 V) or bipolar (±5 V via external resistive network) signal input |
| AGND | Analog ground | Reference return for analog circuitry; must be isolated from DGND at system level |
| VREF | Reference input | Accepts +1.23 V bandgap reference; impedance varies 6–18 kΩ with code |
| CLK | Clock input | Accepts 4 MHz external clock or RC-generated internal clock; internally divided by 2 |
| CS | Chip select | Active-low enable for conversion start and data read; must be synchronized with RD |
| RD | Read strobe | Active-low control for latched data output; determines interface mode (Slow Memory or ROM) |
| TP | Test pin | Must be tied HIGH externally; not usable as signal path or feedthrough |
| BUSY | Status output | Active-low open-drain flag indicating conversion in progress; used for WAIT or interrupt |
| DGND | Digital ground | Return for digital I/O and logic; separate from AGND to minimize noise coupling |
| DB0–DB7 | Data outputs | Three-state, latched parallel outputs (DB0 = LSB, DB7 = MSB); directly drive 8-bit data bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1112CPE+ | Serial SPI interface, 2.7–5.25 V supply, 12-bit resolution, no integrated track-and-hold | Requires external track-and-hold for >10 kHz signals; better resolution but slower effective throughput | Select when serial interface and higher resolution outweigh need for on-chip sample-hold and parallel bus speed |
| ADS7822U | 12-bit SAR ADC, 2.7–5.25 V supply, SPI interface, built-in reference, 1 MSPS max | No parallel bus; requires external clock and driver for microprocessor interface; higher resolution but different timing model | Select when migrating to modern low-voltage designs and accepting serial interface trade-offs for precision |
Compared with MAX1112CPE+ and ADS7822U, the AD7575JNZ delivers deterministic 5 µs latency, parallel 8-bit output, and integrated track-and-hold - making it uniquely suited for legacy 8-bit microprocessor systems where timing predictability and minimal external components are critical.

FAQ
What is the maximum input signal frequency the AD7575JNZ can accurately digitize?
The AD7575JNZ supports full-power signal bandwidth up to 50 kHz - meaning it can digitize full-scale 2.46 VPP sine waves at 50 kHz with ≤1 LSB error. This corresponds to a maximum input slew rate of 386 mV/µs. For accurate representation, the analog input must remain within this bandwidth limit; exceeding it introduces harmonic distortion and quantization error beyond specification.
Does the AD7575JNZ require external calibration for typical use?
No, the AD7575JNZ does not require external calibration in most applications. Its total unadjusted error is specified at ±1 LSB max across temperature, and both offset and full-scale errors are sufficiently low that gain/offset trims are unnecessary for many industrial and instrumentation uses. Calibration circuits are provided in the datasheet only for applications demanding highest linearity.
Can the AD7575JNZ operate with an external clock, and what frequency is recommended?
Yes, the AD7575JNZ accepts an external clock at its CLK pin. A 4 MHz input clock is recommended to achieve the guaranteed 5 µs conversion time and specified accuracy. The internal clock divider reduces this to 2 MHz for core SAR operation. Clock mark/space ratio may vary from 30/70 to 70/30 without affecting functionality.
What is the function of the TP pin on the AD7575JNZ, and how should it be connected?
The TP (Test Pin) on the AD7575JNZ is reserved for factory testing and must be hard-wired to VDD (+5 V) in all operational circuits. It is not intended for signal routing, feedthrough, or any user-defined function. Leaving TP floating or grounding it may cause undefined behavior or failure to acquire valid conversions.
How does the AD7575JNZ interface with an 8085A-2 microprocessor?
The AD7575JNZ interfaces with the 8085A-2 using its Slow Memory Interface mode: CS and RD are asserted during a memory READ cycle, BUSY pulls the READY line LOW to insert wait states, and converted data appears on DB0–DB7 after BUSY returns HIGH. The S0 status signal is used to synchronize CS/RD assertion early in the instruction cycle for reliable WAIT activation.
