概述

Description

AD7535TQ is a high-precision multiplying digital-to-analog converter (MDAC) from Analog Devices. It converts a digital input word into an output that is proportional to the product of the digital code and an external reference, making it ideal for digitally controlled gain, attenuation, and calibration in instrumentation and signal conditioning. The device is designed for good monotonicity, low glitch, wide temperature stability, and fast settling. The “TQ” suffix indicates the packaging (a surface-mount, typically lead-free package). Common uses include programmable gain amplifiers, waveform generation, and precision DAC front ends. For exact specifications—resolution, full-scale range, reference requirements, interfaces (serial/parallel), and package details—consult the AD7535TQ datasheet.

Features

Here are the typical features of the AD7535TQ (datasheet-style, concise):
- 8-bit multiplying DAC (MDAC) with 256 steps; output proportional to D × Vref/256
- External reference required (Vref sets full-scale)
- Serial data input: SPI-compatible 3-wire interface (CS, SCLK, DIN); LDAC option for simultaneous update
- Output modes: voltage output (via external op-amp) or current output (Iout, with external conversion)
- Monotonic, good integral/nonlinearity for 8-bit range
- Fast settling time with low glitch energy
- Wide supply range (single-supply operation typical; check datasheet for exact rails)
- Commercial temperature range (-40°C to +85°C)
- Package: 28-pin TQFP (TQ suffix indicates Thin Quad Flat Package)
- Applications: programmable gain/offset, function generators, calibration, waveform synthesis
Note: exact voltage rails, current/voltage output specifics, and timing should be confirmed in the latest datasheet.

Package

AD7535TQ is in a 16‑lead Thin Quad Flat Pack (TQFP) surface‑mount package.

Pinout

- Pin count: 28 pins (TQFP package).
- Function: 12-bit multiplying digital-to-analog converter (DAC) with a parallel data input interface (D0–D11) and control signals (e.g., LDAC/CLR). It provides a current output (Iout) that typically requires an external op-amp to convert to a voltage; uses a reference input (VREF) and standard supply pins (VDD/VSS).

Manufacturer

- Manufacturer: Analog Devices, Inc. (Analog Devices)
- Company type: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits (e.g., data converters, op-amps, sensors).

Application

AD7535TQ is a 12‑bit multiplying DAC. Typical application areas:
- Precision waveform generation and signal conditioning (sine, ramp, AM/FM modulation)
- Programmable gain/attenuation and calibration in instrumentation and data acquisition
- Automatic test equipment (ATE) signal sources and reference generation
- Closed‑loop control and servo/motor‑control systems
- Analog computing, programmable filters, and other DC/AC signal routing

Equivalent

AD7535TQ is a 12-bit multiplying DAC (MDAC) with SPI-compatible serial input. There isn’t an exact drop-in cross-reference across vendors; equivalents depend on reference mode, output range, speed, and packaging. For alternatives, look for other 12-bit MDACs with SPI from Analog Devices, TI, or Microchip. If a non-multiplying 12-bit DAC is acceptable, SPI DACs such as Microchip MCP4921/4922 or TI DAC75xx/DAC76xx families may serve. Please provide required reference voltage, max update rate, and package to suggest precise matches.
