概述

Description

DAC081CIMK is an 8‑bit multiplying DAC with a current-output stage. It converts an 8‑bit digital input (D0–D7) into a current on the Iout pin that is proportional to the digital code and to an external reference (Vref or Iref). To obtain a usable voltage, you typically load Iout with a precision op-amp in a current‑to‑voltage converter configuration. The “C” indicates the CMOS variant, and “IMK” denotes the package/ordering code. Features commonly include monotonicity and good linearity for an 8‑bit MDAC, suitable for instrumentation, control loops, signal generation, and data‑acquisition front ends. For exact pinout, supply ranges, Iout range, and electrical specs, refer to the official DAC081CIMK datasheet from the manufacturer.

Features

Key features of DAC081CIMK (typical for this family):
- 8-bit multiplying DAC
- Current-output (Iout) device; scale set by external reference
- Parallel 8-bit data input (D0–D7), TTL/CMOS compatible
- Monotonic conversion with good linearity (LSB-level accuracy)
- Requires external precision op-amp and resistor to convert Iout to voltage
- Wide supply range (typical single-supply operation; check variant)
- Small 8-pin IMK package
- Industrial/commercial temperature variants available (range depends on specific part)
Notes: Exact IoutFS, voltage ranges, and temperature specs depend on the specific lot/variant; consult the datasheet for precise numbers.

Package

8-pin plastic DIP (DIP-8) package.

Pinout

- Pin count: 8 pins (8-pin package)
- Function: 8-bit multiplying digital-to-analog converter with current output (Iout). The device converts an 8-bit digital word into a proportional output current driven by an external reference current, for use in analog signal generation.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- Company type: A global semiconductor company specializing in analog, mixed-signal, and digital signal processing integrated circuits, including data converters, amplifiers, and related products.

Application

Applications: precision signal generation and control in instrumentation; programmable current source with Iout-to-V conversion for measurement systems; closed-loop analog control in process/industrial and servo systems; data acquisition front-ends and mixed-signal interfaces; automatic test equipment and calibration rigs; programmable waveform generation and sensor linearization.

Equivalent

DAC081CIMK is an 8‑bit multiplying current‑output DAC. Equivalents include: TI’s DAC081; Burr-Brown/TI DAC0800 family (DAC0800/0802/0804); Analog Devices AD7528 and AD7541/AD7542 (and related AD7520/AD7524). When substituting, verify Iout per LSB, reference input, and packaging (IMK = MSOP‑8/SOIC‑8).
