概述

Description

DAC0832LCV is an 8‑bit multiplying digital-to-analog converter with a current output (MDAC). It takes an 8‑bit parallel word on D0–D7 and, using an external reference current Iref, produces an output current Iout proportional to the code: Iout ≈ (D/256) × Iref for straight binary input. The output is a current source, so you typically convert it to a voltage with an op-amp transimpedance stage (Iout into a feedback resistor). The LCV suffix denotes a specific package/variant (often lead‑free/temperature range) of the DAC0832; consult the datasheet for exact packaging, supply rails, Iref range, and pinout. Common applications include waveform generation, programmable gain/attenuation, and data-acquisition front ends.

Features

Key features of DAC0832LCV:
- 8-bit multiplying DAC with current output
- Parallel binary input (D0–D7)
- Iout proportional to digital input and reference: Iout = (D/256) × Iref
- External reference current Iref sets full-scale current
- Requires external current-to-voltage conversion (op-amp + precision resistor)
- Monolithic IC, available in RoHS/LCV packages (lead-free variants)
- Wide supply range typical: suitable for ±5 V to ±15 V systems
- Generally monotonic and suitable for precision D/A applications
Note: Exact pinout, recommended operating ranges, and electrical characteristics depend on the specific package and lot; consult the current datasheet for precise specs.

Package

8-pin surface-mount package (SOP/SOIC-8).

Pinout

- Pin count: 16 pins (DIP/SOIC package variants, e.g., DAC0832LCV is a 16-pin device).
- Function: 8-bit current-output multiplying digital-to-analog converter (MDAC). It accepts 8-bit digital input and produces a proportional output current (Iout); an external op-amp is typically used to convert Iout to a voltage.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
What kind of company: A multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits used across communications, industrial, automotive, and consumer electronics.

Application

DAC0832LCV is an 8-bit current-output multiplying DAC. It requires an external op-amp or resistor network to convert current to voltage. Applications include:
- Instrumentation and data-acquisition systems
- Analog computing and DSP pre/post processing
- Programmable waveform generation and test equipment
- Control and process-control loops (setpoints, modulation, servo feedback)
- Calibration and programmable voltage/current sources
- Lab benches and educational/Kits

Equivalent

Do you need a pin-for-pin drop-in or just a functionally similar DAC? Pin-compatible equivalents are other members of TI/Burr‑Brown’s DAC0830/0831/0832 family (e.g., DAC0832LV/LCV). For modern substitutes (not pin-compatible), consider 8‑bit current‑output DACs from Analog Devices (e.g., AD532x) or TI’s DAC853x, but verify Iout, Vref and packaging.
