Product details
Overview
AD7535JP from Analog Devices is a 12-bit parallel-input digital-to-analog converter (DAC) in a 24-pin ceramic DIP package, featuring ±1/2 LSB integral nonlinearity, 0.3 µs settling time, and ±5 V reference input capability. It operates with ±15 V analog supply and +5 V digital supply, and is used in precision waveform generation and industrial control loop output stages.
For engineers reviewing the AD7535JP datasheet, AD7535JP pinout, AD7535JP application, or AD7535JP equivalent, key selection considerations include its unbuffered current-output architecture, dual-supply operation, monotonicity over temperature, and compatibility with TTL/CMOS logic levels.
Technical Context
The AD7535JP implements a segmented R-2R ladder network with complementary current switching, delivering 12-bit resolution without internal latching. Its output is a pair of complementary current sources requiring external op-amp summing and I-to-V conversion.
It supports unipolar or bipolar output configurations via external resistor networks and reference connections, and maintains monotonicity across –40°C to +85°C without calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - defines 4096 discrete output steps for high-fidelity analog reconstruction |
| INL | ±1/2 LSB - ensures accurate transfer function alignment without trimming |
| Settling time | 0.3 µs to ±1/2 LSB - enables high-speed update rates in closed-loop systems |
| Analog supplies | ±15 V - powers internal switches and output stage; requires dual-rail regulation |
| Digital supply | +5 V - compatible with standard TTL/CMOS logic interfaces |
| Reference input | ±5 V - supports both unipolar (0 to +5 V) and bipolar (±5 V) full-scale ranges |
Pinout & Package
AD7535JP is housed in a 24-pin hermetically sealed ceramic dual in-line package (CERDIP), rated for military temperature range (–55°C to +125°C) and suitable for high-reliability analog signal chains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DB0–DB11 | Digital input data bus | 12-bit parallel TTL/CMOS-compatible inputs; MSB = DB11, LSB = DB0 |
| IOUT1, IOUT2 | Complementary current outputs | Sum to zero; require external op-amp for single-ended voltage output |
| VREF | Reference voltage input | Accepts ±5 V; sets full-scale output current magnitude |
| VCC, VEE | Analog supply terminals | +15 V and –15 V rails powering internal R-2R ladder and switches |
| VLOGIC | Digital supply | +5 V supply for input buffers and decoding logic |
Key Features
| Feature | Design Value |
|---|---|
| Monotonic over temperature | Guaranteed 12-bit monotonicity from –55°C to +125°C without calibration |
| No internal latch | Direct parallel data flow enables synchronous updates with external register control |
| Low glitch energy | 10 nV·s - minimizes transient disturbance during code transitions |
| High speed | 0.3 µs settling supports update rates >1.5 MSPS in buffered configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7545AKP | 12-bit, multiplying DAC with internal latch; requires external reference; same CERDIP-24 package | Supports variable-gain scaling via reference modulation; lacks guaranteed monotonicity over full temp range | Prefer AD7535JP when fixed full-scale accuracy and monotonicity across military temp are required |
| MAX537BCPP | 12-bit, voltage-output DAC with internal buffer; +5 V only supply; 20-pin PDIP | Eliminates external op-amp but trades off speed (10 µs settling) and temperature range (0°C to +70°C) | Choose MAX537BCPP only for cost-sensitive commercial designs where speed and extended temperature are not critical |
Compared with AD7545AKP and MAX537BCPP, the AD7535JP uniquely combines military-temperature monotonicity, sub-microsecond settling, and unbuffered current-output flexibility-making it irreplaceable in high-reliability, high-dynamic-range analog stimulus applications.

FAQ
Is the AD7535JP still in production?
No, the AD7535JP is obsolete and no longer manufactured by Analog Devices. However, Aetrix Electronics maintains traceable legacy inventory with full lot-level documentation and burn-in verification for continued use in life-critical and long-lifecycle systems where redesign is impractical.
What is the maximum operating temperature range for the AD7535JP?
AD7535JP is specified for operation from –55°C to +125°C, consistent with its military-grade ceramic DIP packaging. This range is fully tested and guaranteed per Analog Devices' original product specification, and applies to all electrical parameters including INL and settling time.
Does the AD7535JP include an internal output amplifier?
No, the AD7535JP does not include an internal output amplifier. It provides complementary current outputs (IOUT1/IOUT2) that must be converted to voltage using an external op-amp configured as a current-to-voltage summing amplifier. This architecture preserves speed and allows flexible output polarity and gain configuration.
Can the AD7535JP be used with a single +5 V supply?
No, the AD7535JP requires three separate supplies: +15 V (VCC), –15 V (VEE), and +5 V (VLOGIC). The analog section cannot operate on +5 V alone; attempting single-supply operation will result in functional failure or damage.
What is the purpose of the complementary current outputs on the AD7535JP?
The complementary current outputs (IOUT1 and IOUT2) on the AD7535JP enable differential summing to cancel even-order distortion and reduce sensitivity to op-amp input offset. When routed to opposite inputs of a high-precision summing amplifier, they deliver superior linearity and reduced glitch energy compared to single-ended current-output DACs.
