The available source material does not provide a complete electrical description of the DSP filters, clocks, output architecture, analog supply limits, or digital I/O levels; these details must therefore be confirmed in the manufacturer datasheet before schematic capture. A typical design would accept I2S audio from a source processor, configure the converter for the desired channel map and sample rate, and route the analog outputs toward line-level amplification. Decoupling and output filtering must follow the manufacturer reference circuit. Because the verified data does not include capacitor values or a full pin assignment, engineers should not infer those values from generic audio guidance. The WM8768GEDS/V is appropriate when the design needs an integrated eight-channel, high-resolution audio DAC rather than a low-channel-count codec. It is also relevant to CD, DVD, home theater, automotive infotainment, and powered-speaker systems, provided the system clocking, supported sample-rate configuration, and analog output topology match the finished board. Current distributor listings show the part available through major electronics distributors, while detailed pricing and lifecycle terms should be checked against live inventory. This page consolidates the verified 24-bit, 192kHz, eight-channel, DSP, I2S, volume-control, 103dB, and SSOP-28 facts while separating confirmed data from missing technical details.

Its 16-TSSOP package supports compact, surface-mount PCB construction, while the listed operating-temperature range of -40°C to +85°C covers industrial-temperature commercial equipment. The manufacturer lists the part as active. Typical applications include LCD television audio paths, DVD players, Blu-ray Disc equipment, set-top boxes, and other consumer systems that convert stereo analog audio into a digital format. Its 192 kHz capability also supports high-resolution audio conversion where the source, clocking, and downstream signal chain support the corresponding sample rate. Designers should treat the analog input network, supply sequencing, clocking, and digital-interface implementation as one signal-chain design. Place input and supply decoupling close to the device, keep analog and digital return currents separated, and verify every digital-audio timing condition against the manufacturer datasheet before releasing the PCB. This page combines the product specifications, sourcing guidance, practical application guidance, package information, and a verified comparison of related audio-conversion options. It is intended to help engineers select the correct converter and plan a reliable implementation without overlooking package, interface, or analog-front-end constraints.

It supports sampling rates from 8 kS/s to 48 kS/s and is housed in a compact 28-W-CSP measuring 2.59 mm by 2.50 mm. The device operates from a 1.71 V to 3.6 V supply and is intended for space-constrained audio capture and voice-recording systems. An audio ADC is a mixed-signal semiconductor that converts an analog microphone or line-level waveform into a digital audio stream. The WM8952ECS/RV belongs to the audio ADC hierarchy, combining an analog-to-digital converter, programmable gain stage, microphone preamplifier, and digital filters into one package. This integration reduces the number of discrete signal-conditioning components required near a microphone capsule or audio input while preserving a standard digital interface for downstream processing. The converter provides 24-bit resolution and supports sampling rates extending to 48 kS/s. Its signal path includes a selectable high-pass filter and four fully programmable notch filters. A mixed-signal automatic level control function with noise gate helps maintain usable recording levels, and the PGA gain can be read back while ALC operation is active. These features are useful in microphone arrays, voice-capture products, and compact consumer audio equipment where environmental noise and changing source levels require active signal conditioning. The digital audio interface supports I2S as well as A-law and μ-law formats. I2S provides a framed, clocked connection to a digital audio processor, host controller, or audio codec, while the companded formats support legacy telephony and voice applications. The manufacturer datasheet describes the device as using an advanced sigma-delta converter design to provide high-quality audio across its 8 kS/s to 48 kS/s operating range. Typical uses include digital voice recorders, headset electronics, mobile audio accessories, microphone preamp modules, and compact industrial monitoring equipment. Its 28-W-CSP footprint is particularly useful when board area is restricted, although careful escape routing and stable analog supply design remain essential because the device combines sensitive analog input circuitry with a high-speed digital interface. Designers should treat the microphone input, digital clock lines, and supply connections as separate critical paths. Keep analog traces short, use a clean low-noise supply, and follow the manufacturer’s recommended application circuit and component values. The 1.71 V to 3.6 V operating range also requires the host system to remain compatible with the converter’s supply and I2S logic levels. This product page combines the manufacturer specifications, verified distributor listings, package information, application guidance, and replacement analysis for engineers evaluating the WM8952ECS/RV. It also distinguishes documented device functions from specifications that require confirmation from the full datasheet, helping designers plan microphone-front-end integration, interface compatibility, and board-level sourcing.

It is packaged in a 42-WLCSP and is designed for portable audio systems, mobile handsets, microphone capture, and line-level stereo recording. Four single-ended or differential analog input connections provide flexible source selection, while each input path supports programmable analog gain up to 60 dB. An audio ADC is a data-conversion IC that converts left and right analog audio signals into digital words for processing, storage, transmission, or playback. The WM8953ECS/RV belongs to the broader ADC/DAC and signal-conversion hierarchy, combining a stereo sigma-delta conversion stage, analog input conditioning, clock generation, and a serial digital audio interface in one compact component. This integration reduces the number of separate clock, capture, and routing blocks required in portable equipment. Key features include 24-bit stereo conversion, operation at 48 kHz, four analog input connections, up to 60 dB of analog gain per input path, and a programmable high-pass filter in the ADC signal path. Single-ended or differential input configurations support microphone and line-input architectures. The integrated PLL and choice of I2S or TDM digital interfaces make the device suitable for systems that need predictable audio-clock recovery and flexible connection to application processors or digital audio processors. The sigma-delta ADC architecture prioritizes high-resolution audio conversion while supporting low-power portable-system requirements. Programmable input gain lets the signal chain be adjusted before conversion, while the high-pass filter can help reduce unwanted low-frequency content in voice and microphone recordings. The WLCSP format supports compact PCB layouts, although careful escape routing, exposed-pad thermal management, and clean analog grounding are essential. Typical uses include mobile-handset voice capture, digital voice recorders, headset microphones, portable audio accessories, stereo line-input equipment, and compact consumer devices that accept digital audio from the WM8953ECS/RV. The same integrated conversion and clocking architecture also suits industrial monitoring modules when power consumption, package area, and audio input count are important constraints. Design the analog input network for the intended source impedance and signal amplitude. Keep microphone and line-input traces short, isolate them from switching nodes, place filtering capacitors close to their associated pins, and maintain a continuous ground reference beneath the analog section. The compact 42-WLCSP requires careful assembly planning because its fine-pitch land pattern and exposed thermal area demand accurate stencil, paste, and reflow control. This product page combines the WM8953ECS/RV device identity, interface and conversion details, application guidance, design considerations, sourcing options, and verified manufacturer information to support engineering selection and PCB planning.
WM8955LSEFL - Stereo Audio DAC with Speaker Driver | Cirrus Logic
The Cirrus Logic Inc. WM8955LSEFL is a stereo digital-to-analog converter with an integrated headphone and speaker driver, a digital audio PLL, and DSP processing for portable audio products. It operates from a 1.71 V to 3.6 V supply, supports 24-bit conversion, and is offered in a compact 32-QFN 5 x 5 mm package. Cirrus Logic markets the device for portable audio applications where several audio functions must share a small circuit area. An audio DAC is a mixed-signal integrated circuit that converts digital audio samples into analog voltage signals for amplifiers, headphones, or loudspeakers. Within the broader signal-chain hierarchy, the WM8955LSEFL combines a digital-to-analog converter, digital signal processing, clock generation, and output-driver functions. Integrating these blocks reduces the component count and board area required around a portable device's audio output stage. Key device attributes include two output channels, 24-bit resolution, and a 48 kSPS audio sampling rate listed for the WM8955LSEFL. The manufacturer also identifies DSP and I2S interfaces, along with separate analog and digital supply domains. A related WM8955LSEFL/R variant is described as supporting a 96 kSPS sampling rate, demonstrating the family's capability for higher-rate digital audio transmission. The integrated digital processing and PLL allow the converter to derive the required audio clock from a system reference and support multiple serial audio formats. The manufacturer lists DSP and I2S as the principal data interfaces, making the device suitable for application processors and portable audio hosts that provide digital sample streams. Its low-voltage operation suits battery-powered equipment where analog and digital rails commonly sit between 1.8 V and 3.3 V. Typical uses include portable media players, smartphones, tablets, digital audio accessories, and compact consumer products. The WM8955LSEFL can also serve as the output stage in a portable speaker system, reducing the need for separate analog codec and output-amplifier blocks. System designers should confirm the selected host interface, required sampling rate, output configuration, and load impedance against the manufacturer datasheet before releasing a PCB. A key design consideration is the relationship between supply voltage, output drive, and thermal dissipation. Headphone and speaker outputs dissipate power as voltage drop across the output transistors, so sustained high-level playback can raise junction temperature even though the digital interface consumes comparatively little power. Reserve copper around the exposed pad, follow the manufacturer's layout guidance, and place output protection components where they cannot compromise the intended load drive. This page consolidates device specifications, interface details, application guidance, and component-selection considerations for engineers evaluating the WM8955LSEFL in compact audio systems.
WM9081GICN/V - 24-Bit Mono DAC with 2.6W Amplifier | Cirrus Logic
The Cirrus Logic WM9081GICN/V is a mono 24-bit digital-to-analog converter with an integrated 2.6 W Class AB/Class D speaker amplifier, supplied in a 28-pin QFN package measuring 4 x 4 mm. It accepts I2S, DSP, LJ, and RJ digital audio data and is intended for space-constrained portable equipment where a single device must provide high-resolution digital-to-analog conversion and speaker drive. The operating voltage range is 1.71 V to 3.6 V, and the specified temperature range is -40 °C to +85 °C. An audio DAC converts digital audio samples into an analog voltage signal suitable for an audio amplifier or speaker driver. The WM9081GICN/V combines that conversion function with a programmable output stage and integrated mobile parametric equalization. Its fully programmable EQ coefficients allow speaker and enclosure characteristics to be optimized, while programmable dynamic-range control supports louder playback at low listening levels. The result is a compact audio signal-chain component that reduces the need for separate DAC and speaker-driver packages. The device supports 2-wire, 3-wire, 4-wire, and hardware control modes, with digital audio formats including LJ, RJ, I2S, and DSP. TDM support broadens its usefulness in multi-channel portable audio systems where several codec or converter functions share one digital bus. A thermal-shutdown interrupt provides a system-level indication that the integrated output stage has entered its protected operating condition. The manufacturer also identifies programmable gain as part of the device feature set. Typical applications include portable media players, mobile phones, compact personal audio systems, docking speakers, and other battery-powered products with an integrated single-speaker output. Placing the DAC and amplifier in one package reduces board area, external component count, and the number of signal connections between the digital audio source and the speaker. Design layouts should follow the manufacturer datasheet for decoupling, exposed-pad grounding, and analog output routing. Keep the digital interface traces away from the speaker output and amplifier supply nodes to reduce the chance of switching-edge coupling into the audio path. Confirm the configured control mode and digital format in firmware before enabling the output stage. This page organizes the WM9081GICN/V specifications, application guidance, package details, and sourcing information into a single engineering reference for compact mono audio output designs.
X9313UST1 - 50kΩ 32-Tap Digital Potentiometer SOIC-8 | Renesas
The Renesas X9313UST1 is a digitally controlled potentiometer (XDCP™) housed in an 8-pin SOIC package with a fixed end-to-end resistance of 50 kΩ and 32 resistive taps. It provides a single-channel, non-volatile, up/down wiper interface through three logic input pins (U/D, INC, CS) and stores the last wiper position through on-chip nonvolatile memory that retains setting across power cycles. The 32-tap resolution gives approximately 1.0% per-step resolution across the resistor array. Background context: a digital potentiometer (often abbreviated "digi-pot") is a solid-state, semiconductor replacement for a mechanical potentiometer or trim pot. Digi-pots sit within the broader data-acquisition and analog-signal-conditioning hierarchy, alongside DACs and digital rheostats, and they belong to the Renesas XDCP™ family. Unlike mechanical pots, they are programmable by host firmware, never wear from mechanical actuation, and ship in surface-mount packages suitable for reflow soldering and dense PCB layouts. Key features include a low 1 mA (typical) standby current, terminal voltages up to ±5 V across the resistor array, a 1.0% end-to-end resistance tolerance, and a wiper current rating up to approximately ±1 mA continuous, with peak surge handling to 10 mA. The 3-wire serial interface consumes only three MCU GPIO pins and is compatible with 5 V logic. The internal architecture pairs a polysilicon resistor array with CMOS wiper switches and a non-volatile memory cell that latches the last wiper position before power-down. Three control inputs (CS, INC, U/D) implement a step-and-direction interface: CS enables the chip, INC clocks each tap step, and U/D selects up or down direction. Power-on recall places the wiper on the stored value with deterministic behavior. Typical applications are audio volume/balance control, LCD contrast/brightness trimming, programmable voltage references, sensor calibration, and parameter-set storage where an MCU must hold a setting through power-down. Because the wiper retains state without external EEPROM, designers can eliminate a serial EEPROM and reduce BOM cost in many calibration circuits. When designing with the X9313UST1, respect the maximum terminal voltage (±5 V across the resistor terminals) and verify that pin 8 is correctly identified in PCB layout - the part is widely second-sourced and a small number of look-alike 8-pin digi-pots swap the GND and VL pin positions. Add a 0.1 µF decoupling capacitor close to the supply pin and confirm that CS is not allowed to float. This page combines the Renesas datasheet specifications, current distributor pricing, pin-compatible cross references, and practical layout notes not always covered in the original datasheet, providing engineers a single-page engineering brief for the X9313UST1.
XR4151CP-F - V/F Converter, 8-22V, 100kHz | MaxLinear
The MaxLinear XR4151CP-F is a monolithic voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter IC supplied in an 8-pin PDIP through-hole package. It accepts a single-ended analog input voltage of 0 to 10 V (or -10 V to 0 V with appropriate biasing) and produces a proportional output pulse train whose frequency is linearly related to the input amplitude. The maximum full-scale frequency is 100 kHz with a usable range of 1 Hz to 100 kHz and a typical linearity error of +/-0.05%. A voltage-to-frequency converter (V/F or VFC) is a mixed-signal building block that translates a continuous analog voltage into a stream of digital pulses whose repetition rate is precisely proportional to the input magnitude. VFCs sit within the broader hierarchy of analog-to-digital conversion techniques alongside successive-approximation ADCs, dual-slope integrating ADCs, and sigma-delta modulators, and are valued for their inherent monotonicity, excellent noise rejection, and galvanic isolation-friendly pulse output that can be transmitted through optocouplers or long cables. Key features of the XR4151CP-F include a supply voltage range of 8 V to 22 V, very high noise rejection, inherent monotonicity over the full dynamic range, a single open-collector output stage that can interface with CMOS/TTL logic, and the ability to operate in reverse as a frequency-to-voltage converter with a small number of external components. The -F suffix denotes the lead-free, RoHS-compliant version of the original XR4151CP, while both share the same die and pinout. The internal architecture consists of a precision current source, a high-gain operational amplifier, a comparator, and a one-shot timing network. The op-amp drives a current into an external RC network whose charging time determines output pulse width; this architecture eliminates the missing-pulse and non-monotonic errors that plague simple charge-pump VFCs. The dedicated low-leakage input protection on pin 7 prevents the inverting input from being driven below ground, eliminating the need for an external clamp diode in most applications. Typical applications include precision analog-to-digital conversion where the output is fed to a counter or microcontroller capture input, isolated analog signal transmission across 4-20 mA replacement links, motor speed control via frequency-to-voltage conversion of tachometer pulses, and long-integral analog signal conditioning in industrial weighing, temperature, and pressure transmitters. When designing with the XR4151CP-F, choose the external timing resistor and capacitor first - the resistor sets the input current range and full-scale frequency, while the capacitor sets the one-shot pulse width. Add a 0.01 uF bypass capacitor close to the supply pin and use low-leakage timing components to maintain the 0.05% linearity specification. This page synthesizes distributor pricing, lead-time, pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single-source decision framework for new designs and legacy XR4151CP replacement.
XRD8775AID-F - 8-Bit 20MSPS Flash ADC, 5V CMOS | MaxLinear
The MaxLinear (formerly Exar) XRD8775AID-F is an 8-bit, 20 MSPS analog-to-digital converter using a 2-step flash architecture in a 20-pin SOIC wide-body package. It operates from a single 5V supply, accepts analog inputs from 0V to VDD, supports a reference range of 1V to VDD, and integrates an internal sample-and-hold function that eliminates the need for an external track-and-hold amplifier. Typical power consumption is 75 mW (excluding reference current), enabling low-power system designs. An analog-to-digital converter (ADC) is a data converter that translates real-world continuous analog signals into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Flash and 2-step flash ADCs achieve the highest sampling rates among all ADC architectures by using parallel comparator banks, making them well-suited for video, instrumentation, and high-speed control loops. The XRD8775AID-F belongs to the hierarchy: ADC -> data converter -> signal chain IC -> mixed-signal semiconductor. Key specifications include 8-bit resolution, 20 MSPS sampling rate, parallel digital interface, single 5V analog supply, internal S/H, 0V-to-VDD analog input range, and -40C to +85C operating temperature. The wide-body 20-SOIC package (0.295 inch / 7.50 mm width) provides robust thermal performance and ease of hand-soldering for prototyping. The part is offered in tube packaging for manufacturing. The 2-step flash architecture trades a small number of comparator channels for a substantial reduction in die area and power consumption versus a full flash design, while still maintaining video-grade 20 MSPS throughput. Internal S/H bandwidth supports IF undersampling and video bandwidth applications. The CMOS process ensures low power, latch-up free operation, and stable performance across the industrial temperature range. Typical applications include video digitisation, CCD camera front ends, digital oscilloscopes, ultrasound front-end preprocessing, IF sampling in communications receivers, and industrial process control loops. The combination of wide analog input range and integrated S/H simplifies board-level design for low-channel-count high-speed data acquisition. When designing with this part, place a 0.1 uF ceramic decoupling capacitor as close as possible to the VDD pin and a bulk tantalum or electrolytic capacitor on the analog supply rail. The reference pin requires a low-impedance source; use an op-amp buffer or a dedicated reference IC if the application demands better than 8-bit absolute accuracy. This page synthesises distributor pricing, parametric drop-in alternatives from same-brand and cross-brand portfolios, and practical design notes that complement but do not duplicate the manufacturer datasheet.
XRD8775AIU - 8-Bit 20MSPS Flash ADC, 20-SSOP | MaxLinear
The MaxLinear (formerly Exar) XRD8775AIU is a monolithic CMOS 8-bit flash analog-to-digital converter delivering up to 20 MHz sampling rate in a 20-pin SSOP package. It integrates an internal sample-and-hold amplifier, operates from a single +5 V supply, and consumes only 75 mW typical (excluding external reference current). The input voltage range spans 0 V to VDD with a flexible reference voltage range of 1 V to VDD, allowing direct interface with single-supply analog signal chains. An 8-bit flash ADC is a parallel-architecture converter that uses 2^N-1 comparators to digitize an analog input in a single clock cycle, delivering the fastest conversion latency of any ADC topology at the cost of exponential die-area growth with resolution. Flash converters therefore dominate sub-10-bit, multi-MHz applications such as video digitizers, digital oscilloscope front ends, and radar IF samplers where latency and sampling rate, not resolution, are the primary constraints. Key specifications of the XRD8775AIU include 8-bit resolution, 20 MSPS maximum sampling rate, internal S/H, single +5 V supply operation, 75 mW typical power dissipation, latch-up-free CMOS construction, and 2000 V minimum ESD protection. The parallel data interface simplifies connection to FPGAs, ASICs, or microcontrollers without requiring a serial programming sequence. The 20-SSOP package suits space-constrained boards where analog and digital grounds can be partitioned for noise immunity. Architecturally, the device uses 255 parallel latched comparators feeding a priority encoder that generates an 8-bit thermometric code, then a binary encoder delivers the output word in a single clock edge. The internal sample-and-hold amplifier stabilizes the input within the aperture window, which is critical for full-scale inputs above 10 MHz to avoid code-edge distortion. The reference ladder is externally driven, giving the designer freedom to set the LSB size by scaling VREF between 1 V and VDD. Typical applications include digital oscilloscope input channels, video digitizers, CCD imaging front ends, radar IF sampling, ultrasound beamforming pre-processors, and industrial data-acquisition front ends. The 75 mW dissipation also suits portable test gear and battery-powered instrumentation where the internal S/H eliminates an external track-and-hold IC. Design tip: Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VDD pin and a bulk 10 uF tantalum capacitor near the analog ground island; route the 8-bit parallel bus with matched trace lengths to prevent sub-LSB timing skew at the full 20 MSPS rate. Also bypass the external VREF pin with 10 uF to keep the internal resistor ladder stable and reduce sparkle-code errors. This page synthesizes distributor pricing, verified drop-in 8-bit flash ADC alternatives, and practical PCB layout guidance that goes beyond the manufacturer datasheet, helping engineers shorten the BOM-sourcing and design-in cycle for this legacy flash converter.
XRD8775AIU-F - 8-Bit 20MSPS Parallel ADC | MaxLinear | Exar
The MaxLinear XRD8775AIU-F is an 8-bit resolution, 20MSPS sampling rate analog-to-digital converter (ADC) with a single-ended input and parallel digital data interface, housed in a 20-pin SSOP package. Originally introduced by Exar Corporation and now sold under MaxLinear, the part is specified as IC ADC 8BIT PAR 20MSPS 20SSOP and operates from a single 5V analog supply. An analog-to-digital converter (ADC) is a data-acquisition integrated circuit that samples continuous analog signals and converts them into discrete digital codes. Flash ADCs like the XRD8775AIU-F use an array of comparators to deliver the fastest conversion times, typically reserved for video, instrumentation, and high-speed control loops where sub-microsecond conversion latency is mandatory. The 8-bit, 20MSPS segment sits at the entry level of high-speed conversion and is well suited for digitizing video bandwidths, IF signals, and oversampled measurement channels. Key features per the manufacturer datasheet include 8-bit resolution, 20 MHz maximum sampling rate, an internal sample-and-hold (S/H) function, a single-ended analog input range of 0V to VDD, a reference input range of 1V to VDD, and typical power consumption of 75 mW (excluding reference current). The device provides latch-up free operation and ESD protection rated at 2000V minimum, simplifying board-level robustness. The XRD8775AIU-F uses a flash converter architecture with a 1:1 S/H-to-ADC ratio, providing a single simultaneous sampling channel with a parallel 8-bit output bus. This architecture removes the need for an external track-and-hold amplifier in most digitizer front ends and simplifies downstream FPGA or ASIC capture logic. Typical applications include standard-definition video digitizers, CCD/camera signal chains, ultrasound front-end signal conditioning, IF sampling for communications receivers, and high-speed industrial inspection systems. The 20MSPS capability comfortably handles component video and baseband IF signals up to about 7 MHz of input bandwidth. When designing with this part, ensure the analog input drive network presents low source impedance at the Nyquist frequency and that the reference pin is decoupled with a low-ESR capacitor placed within 5 mm of the package pin. Because the part is sourced via MaxLinear (after the Exar acquisition) and is listed as obsolete in some distributor databases, confirm long-term supply before committing to high-volume production.
XRD8785AID-F - 8-Bit 20MHz Flash ADC, 24-SOIC | MaxLinear
The MaxLinear (formerly Exar) XRD8785AID-F is an 8-bit, 20 MSPS flash analog-to-digital converter (ADC) with one input channel, housed in a 24-pin SOIC wide-body package. It uses an advanced 5V CMOS process and provides 8-bit resolution, up to 20 MHz sampling rate, an internal sample-and-hold function, and a single 5V analog supply. The device accepts an input range of 0V to VDD and a reference range of 1V to VDD, making it suitable for general-purpose digitizing of unipolar signals. Latch-up free operation and a minimum 2 kV ESD protection rating ensure robust real-world handling during board assembly and field use. An 8-bit flash ADC is the fastest ADC architecture, using 2^8 (256) parallel comparator-latch cells and a resistor reference ladder to convert an input voltage to a digital code in a single clock cycle. Flash ADCs occupy the low-resolution, very-high-speed corner of the converter family tree: SAR ADCs (successive approximation) offer higher resolution at lower speed, while pipelined ADCs sit between them. Flash ADCs therefore dominate in digital oscilloscopes, video digitizers, CCD imaging front-ends, radar IF sampling, and digital receiver IF strips where sub-100 ns latency matters more than 12-16 bit precision. Key features of the XRD8785AID-F include 5V single-supply operation, a typical power dissipation of 75 mW excluding the reference current, an internal S/H that removes the need for an external track-and-hold amplifier, and three-state CMOS-compatible digital outputs. Its flash topology delivers full-code conversion in a single clock, and the 24-SOIC package exposes all digital outputs and the S/H control pins for easy parallel interfacing to FPGAs, microcontrollers, or display controllers. Typical applications for the XRD8785AID-F include digital oscilloscope front-ends, video digitizers, CCD imaging signal chains, instrumentation digitizers, and communication IF sampling. The simple 5V/CMOS interface, parallel output bus, and low 75 mW dissipation also suit it for board-level prototyping where a fast acquisition path is needed without the cost of a precision ADC. When designing with this device, follow the datasheet's recommended decoupling and reference bypassing carefully. Place a 0.1 uF ceramic bypass close to the analog supply pin and a 10 uF bulk tantalum or ceramic capacitor nearby; bypass the reference pin with a low-impedance capacitor so the high-speed comparator ladder does not see reference bounce. For engineers evaluating the XRD8785AID-F, DigiKey, Mouser, and Octopart list it as an active MaxLinear SKU with multiple distributor stocks, while legacy Exar datasheet PDFs remain valid references. This page goes beyond the basic datasheet by consolidating distributor pricing tiers, cross-brand drop-in alternatives, and practical PCB/thermal layout notes.
XRD8785AIDTR-F - 8-Bit 20MSPS Flash ADC, 24-SOIC | MaxLinear
The MaxLinear XRD8785AIDTR-F is an 8-bit flash analog-to-digital converter (ADC) sampling at up to 20 MSPS with a single 5V supply, housed in a 24-pin wide-body SOIC package (0.295 inch / 7.50 mm body width) shipped on tape and reel. Key electrical parameters include 8-bit resolution, 20 MHz maximum sampling rate, one single-ended analog input, internal sample-and-hold (S/H), external or internal reference option, 0V-to-VDD analog input range, 1V-to-VDD reference range, 75 mW typical power consumption (excluding reference), and an operating temperature range of -40C to +85C. The suffix "D" indicates the 24-SOIC package, "T" indicates tape-and-reel packaging, and "R-F" denotes the MaxLinear / Exar part-numbering convention. A flash ADC is a type of analog-to-digital converter that uses a parallel bank of 2^n comparators to convert an analog signal to an n-bit digital code in a single clock cycle, achieving the highest sampling speed of any ADC architecture. The hierarchy is: ADC -> data converter -> data acquisition IC -> mixed-signal IC -> semiconductor. Flash converters excel in applications demanding low latency and wide input bandwidth, but they trade resolution and power efficiency against sampling speed. The XRD8785AIDTR-F occupies the entry-level 8-bit, 20 MSPS tier, which is the typical sweet spot for video digitisation, ultrasound receive beams, and intermediate-frequency (IF) sampling in low-cost communications receivers. Key features of this device include a parallel (TTL-compatible) digital output bus, internal S/H front-end, latch-up free CMOS construction, ESD protection on analog and digital pins, single 5V supply operation, and low power consumption at 75 mW typical. The 24-SOIC wide-body package measures approximately 15.4 mm x 7.5 mm x 2.35 mm, providing generous die-to-board clearance for through-hole or socketed prototypes. The device is built on a 5V CMOS process, providing low power consumption, latch-up immunity, and ESD protection. Internal reference mode simplifies bill-of-materials, while external reference mode lets designers optimise linearity or temperature drift for instrumentation-grade designs. Typical applications include video digitisation, digital oscilloscope front-ends, IF sampling in communications receivers, CCD/CMOS image sensor digitisation, and industrial control loop sampling. When designing with this device, ensure the analog input signal is bandwidth-limited to less than the Nyquist frequency (10 MHz for 20 MSPS) and that the external reference decoupling capacitor is placed within 5 mm of the REF pin to prevent kickback noise from corrupting the conversion.
