概要

Description

DAC0832LCV is an 8-bit multiplying digital-to-analog converter with a current output. It converts a binary code on D0–D7 into a proportional output current set by a reference current Iref. The device does not directly produce a voltage; you obtain Vout by feeding Iout into a transimpedance stage (usually an op-amp with a feedback resistor), e.g., Vout ≈ −Iout × Rf (sign depends on configuration). The full-scale current is determined by Iref, and Iout ≈ (Iref/256) × Code (Code = 0–255). Key pins include D0–D7, Iout, Iref/Vref, Vcc, and GND; inputs are compatible with TTL/CMOS levels per the datasheet. The LCV suffix indicates a specific packaging/temperature grade of the DAC0832 family. Applications include waveform generation, data acquisition, and instrumentation where a controllable current (into a resistive load) is preferred over a direct voltage output.

Features

Here are the typical features of the DAC0832LCV:
- 8-bit multiplying DAC (MDAC)
- Current-output DAC; requires external I–V conversion (op-amp) to get a voltage
- Binary input with TTL/CMOS-compatible data lines
- Can operate in bipolar or unipolar mode via reference and code
- Monotonic with good linearity (DNL/INL within spec)
- Fast settling suitable for many DAC applications
- Low power consumption
- Available in the LCV package (8-pin small-outline style)
Note: exact figures (Iout full-scale, supply range, settling time) are in the datasheet; consult for precise values.

Pinout

- Pin count: 14 pins (DIP/SOIC variants such as DAC0832LCV)
- Function: 8‑bit current‑output multiplying digital‑to‑analog converter. Converts an 8‑bit digital input (D0–D7) into a proportional output current Iout, scaled by a reference current Iref (Iout ≈ (D/256) × Iref); requires an external op-amp to convert the current to a voltage.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, digital, and mixed-signal integrated circuits for a wide range of electronics and industrial applications.

Application

DAC0832LCV is an 8‑bit multiplying DAC with current output. Key applications:
- Digital-to-analog conversion in microprocessor/DSP systems (Iout → Vout via an op‑amp)
- Analog control loops (process, motor, temperature) needing programmable reference/offset
- Test, measurement, and instrumentation (signal generation, calibration sources)
- Data-acquisition front-ends (scale/offset generation for sensors)
- Servo/feedback systems requiring adjustable analog signals
- Low-cost embedded systems where a voltage-output DAC isn’t needed or to minimize I/O lines
Note: use an external I–V converter for voltage output.

Package

DAC0832LCV uses an 8-pin DIP (DIL) through-hole package.
