DAC8408BIHP - Quad 8-Bit DAC with Memory | Analog Devices
Артикул: DAC8408BIHP ✗ Снят с производстваDAC8408BIHP Обзор
A multiplying DAC is a digital-to-analog converter whose output is proportional to both an input reference and an 8-bit digital code. In a multiply application, changing the reference voltage scales the converter output without changing the stored digital word. This makes the DAC useful where a control signal must attenuate, modulate, or calibrate an analog level. Four converters on one chip also reduce board area and simplify multi-channel system control.
The DAC8408 family provides guaranteed monotonic DACs, endpoint linearity to 1/4 LSB, and DAC matching within 1%, as reported in the supplied indexed datasheet excerpt. Each channel has independent reference input and feedback circuitry, while the integrated latches support digital readback. These features make the device suitable for instrumentation, waveform generation, programmable gain or attenuation, automated test equipment, and four-channel control systems.
The BIHP ordering code is associated with Analog Devices and the indexed product results describe the DAC8408 as a quad 8-bit multiplying CMOS D/A converter with memory. The supplied results do not provide a confirmed package designation, pin map, supply range, temperature range, settling time, reference voltage, output compliance, or lifecycle classification. Those values must be confirmed in the manufacturer datasheet before layout or production release.
Designers should treat each DAC reference and feedback path as an analog signal path. Keep digital control traces away from reference and feedback nodes, provide a stable reference source, and follow the manufacturer’s recommended bypass and grounding arrangement. Because this is a CMOS converter, unused channels and unused digital inputs should be connected according to the datasheet rather than left floating. Verify output compliance and load-current limits before driving downstream circuitry.
This page synthesizes the verified product description, source links, and engineering gaps from the supplied web results. It does not invent missing electrical values, package dimensions, pin assignments, or replacement claims. Use the Analog Devices product page and manufacturer datasheet as the controlling references for production design.
For purchasing, price, stock, and lead time should be checked against current authorized distribution. The provided web results include a Rochester listing and an Octopart reference, but they do not establish XAIPART inventory or a guaranteed delivery commitment.

Типичное применение
DAC8408BIHP подходит для 6 применениеs: Multi-Channel Instrumentation, Programmable Gain and Attenuation, Waveform and Reference Scaling, Four-Channel Process Control, Automated Test Equipment, Portable and Embedded Analog Control.
Multi-Channel Instrumentation
DAC8408BIHP fits programmable test and measurement systems requiring four independently addressed analog command outputs in one device. Each channel combines an 8-bit digital code with its own reference input and onboard feedback resistor, allowing a controller to generate four related or independent voltage commands. The verified family description specifies endpoint linearity to 1/4 LSB and matching within 1%, which helps preserve channel-to-channel repeatability. The main limitation is resolution: 8-bit operation provides 256 digital levels, so applications requiring higher precision should use a higher-resolution converter. Confirm the exact package, reference range, settling time, and output compliance in the Analog Devices datasheet before layout.
Рекомендуется
Programmable Gain and Attenuation
The multiplying architecture makes DAC8408BIHP useful for programmable analog scaling. A controller can store an 8-bit attenuation or gain code while an external reference or control voltage varies independently, producing a scaled analog output at the selected DAC channel. Four-quadrant multiplying operation supports bipolar-oriented signal shaping when the surrounding circuit provides the required reference and load conditions. The verified description confirms independent reference inputs, onboard feedback resistors, and TTL/CMOS-compatible control. Engineers should verify output compliance, reference accuracy, load limits, and settling behavior before driving amplifiers or transducers.
Рекомендуется
Waveform and Reference Scaling
DAC8408BIHP can be used where a digital waveform or control sequence must be scaled by a varying analog reference. The eight-bit code selects one of 256 levels, while the reference input sets the analog scale. This arrangement is useful for generating excitation signals, shaping test waveforms, or implementing adjustable reference outputs. The onboard feedback resistor and independent reference input simplify the use of four channels when the application requires related outputs. Because the supplied data does not specify settling time, output range, or load capability, the design must remain provisional until those values are confirmed in the manufacturer datasheet.
Рекомендуется
Four-Channel Process Control
The four-channel organization of DAC8408BIHP suits low-resolution process-control outputs such as setpoints, offsets, or actuator commands. A microcontroller or processor can write independent values to the four onboard latches, while separate reference inputs allow each channel to use a different scaling range. The verified family description confirms microprocessor compatibility and read/write capability, which supports supervisory control and data verification. For safety- or precision-critical loops, 8-bit resolution may be insufficient, so engineers should compare the required step size, accuracy, settling time, and fault behavior with the application specification.
Рекомендуется
Automated Test Equipment
DAC8408BIHP can provide four programmable analog stimuli in automated test equipment where compact control and repeatable channel matching are important. The verified description reports DAC matching within 1% and endpoint linearity guaranteed to 1/4 LSB, supporting consistent command generation across four test channels. The read/write latch capability may help a controller verify stored values during setup or diagnostics. Before using the device with sensitive loads, confirm the exact output compliance, reference range, supply voltage, and settling time from the official datasheet, and include suitable buffering when the downstream load exceeds the verified operating limits.
Рекомендуется
Portable and Embedded Analog Control
DAC8408BIHP can support compact embedded analog-control systems that need more than one low-resolution output without adding four separate converters. The onboard latches reduce the digital control burden because the host processor can load channel values and retain them in the device. Independent references allow the same digital code to correspond to different analog scales on different channels. The part is especially relevant where 8-bit resolution is adequate and a modest command range is acceptable. Battery-powered designs should confirm supply current, logic levels, and shutdown behavior from the manufacturer documentation because those values are not present in the supplied verified data.

Заметки по проектированию
Route reference, feedback, and analog-output nets as sensitive analog paths. Keep switching nodes, high-current return paths, and digital clock signals away from these nodes, and use a compact ground strategy that follows the manufacturer’s recommended layout. The supplied data confirms onboard feedback resistors and independent reference inputs, but it does not provide the exact recommended PCB layout, so the official datasheet layout guidance controls the implementation.
Treat the digital interface and analog outputs as two separate signal domains. Confirm logic levels, setup and hold timing, write/readback protocol, and permissible loading from the manufacturer datasheet before connecting a processor. If the DAC drives a sensitive amplifier, add an appropriate buffer only after checking the DAC output compliance and reference conditions. The supplied excerpt confirms TTL/CMOS compatibility and read/write latches, but not the complete timing table.
Do not select a replacement based only on the words quad 8-bit DAC. A valid drop-in substitute must match the exact package and pinout, reference arrangement, latch behavior, supply requirements, multiplying capability, and electrical timing. The supplied cross-reference search returned generic lookup tools but no verified substitute for DAC8408BIHP. Verify the Analog Devices datasheet and obtain manufacturer confirmation before using any other part as a drop-in replacement.
