XRD87L75AIUTR-F Übersicht
An ADC (Analog-to-Digital Converter) is a data acquisition integrated circuit that converts continuous analog signals into discrete binary codes at a defined sampling rate. Within the broader hierarchy, this device sits as: ADC -> data converter -> data acquisition IC -> mixed-signal semiconductor. The 2-step flash architecture is a variant of the flash ADC that halves the comparator count versus a full flash, reducing both die cost and input capacitance, while the integrated S/H eliminates the need for an external track-and-hold amplifier in most applications.
Key features include 8-bit resolution at 10 MHz sampling rate, single 3.3 V supply operation with 25 mW typical power dissipation (excluding external reference current), parallel digital output interface for direct connection to microcontrollers, DSPs, or FPGAs, and latch-up free CMOS construction for robust ESD/handling performance. The internal sample-and-hold eliminates external S/H requirements and supports full Nyquist bandwidth input frequencies, making the device suitable for general-purpose digitizing tasks where cost-per-channel matters.
The XRD87L75AIUTR-F architecture uses a 2-step flash topology with on-chip S/H, error correction, and a parallel CMOS-compatible output bus. Its low input capacitance and high input bandwidth reduce drive-amplifier loading, and the part is specified to operate from a single 3.3 V rail, simplifying power tree design in 3.3 V logic systems. The internal reference buffer accepts a user-supplied reference from 1 V to VDD for system-level gain calibration. The -F suffix denotes the lead-free, RoHS-compliant tape-and-reel packaging option.
Typical applications include video digitizing and graphics capture, CCD/CIS sensor front-ends, digital oscilloscope front-ends, baseband IF sampling, low-cost digital imaging, and portable instrumentation. The 8-bit/10 MSPS combination aligns well with standard-definition video bandwidths (~5 MHz) and consumer imaging throughput requirements.
When designing with this part, place the input RC anti-alias filter directly at the analog input pin and provide a low-impedance reference buffer because the reference pin input current scales with sampling rate. Parallel output bus traces should be length-matched and series-terminated near the ADC to limit digital switching noise coupling back into the analog input. Decouple VDD with both a 0.1 uF ceramic and a 10 uF bulk capacitor placed within 5 mm of the supply pin.

Typische Anwendungen
XRD87L75AIUTR-F ist geeignet für 6 Anwendungs: Standard-Definition Video Digitizing, Digital Oscilloscope Front-End, CCD/CIS Sensor Front-End, Baseband IF Sampling, Low-Cost Digital Imaging, Portable Instrumentation.
Standard-Definition Video Digitizing
The XRD87L75AIUTR-F's 8-bit resolution at 10 MSPS aligns directly with standard-definition video bandwidth (~5 MHz video, sampled at 10 MSPS to satisfy Nyquist). According to the Exar/MaxLinear datasheet, the internal S/H supports full-Nyquist input bandwidth, and the parallel 8-bit CMOS output bus streams pixels directly into an FPGA or video encoder. Unlike a high-resolution SAR ADC, this part delivers low-latency conversion, no pipeline delay, and a low 25 mW typical power dissipation for portable capture cards.
Empfohlen
Digital Oscilloscope Front-End
The XRD87L75AIUTR-F's 2-step flash architecture with internal S/H gives the low-latency, real-time sampling that a DSO front-end requires. Per the Exar/MaxLinear datasheet, the part digitizes a single-ended input up to VDD, accepting a 1V-VDD external reference so the engineer sets full-scale to match the front-end attenuator. The 20-SSOP footprint keeps the analog section on a small board area, and the parallel output bus feeds an FPGA capture buffer directly without complex serial-deserialize logic.
Empfohlen
CCD/CIS Sensor Front-End
The XRD87L75AIUTR-F is well suited for digitizing CCD or CIS image sensor analog outputs at line-scan speeds up to 10 MSPS. Per the MaxLinear datasheet, the 1:1 internal S/H ratio and single-ended 0V-VDD input accept CIS-style video signals directly, and the parallel CMOS digital output drives an FPGA line buffer in real time. The 3.3 V single-supply operation matches typical CIS bias rails, eliminating the need for level shifting, and the 25 mW typical power dissipation keeps scanner/fax/copier thermal budgets on track.
Empfohlen
Baseband IF Sampling
The XRD87L75AIUTR-F's 10 MSPS throughput makes it viable for narrowband baseband IF sampling in low-cost software-defined radio and communication receivers. According to the Exar/MaxLinear datasheet, the internal S/H and single 3.3 V supply keep the receiver's analog section compact, and the parallel CMOS outputs route directly into a baseband DSP or FPGA. An external anti-alias RC filter at AIN limits out-of-band noise, and the 1V-VDD external reference sets full-scale to match the IF chain's signal swing.
Empfohlen
Low-Cost Digital Imaging
The XRD87L75AIUTR-F provides 8-bit/10 MSPS throughput for cost-sensitive digital still camera or webcam front-ends, where 8-bit color depth is acceptable. Per the MaxLinear datasheet, the 2-step flash architecture is cheaper than full-flash and faster than a SAR, hitting the right cost/speed point for consumer imaging. The 20-SSOP footprint enables compact PCB layouts, and the parallel output bus interfaces directly to image-sensor ASICs or entry-level microcontrollers with DMA, avoiding a high-speed serial ADC's protocol stack.
Empfohlen
Portable Instrumentation
The XRD87L75AIUTR-F's 25 mW typical power dissipation and 3.3 V single-supply operation suit handheld oscilloscopes, data loggers, and field-test gear where every milliwatt matters. According to the MaxLinear datasheet, the 8-bit/10 MSPS throughput captures transient signals while the internal S/H eliminates external track-and-hold components, shrinking BOM and PCB area. The 20-SSOP package supports dense board layouts typical of portable equipment, and the -F suffix part is lead-free and RoHS compliant for global sale.

Wichtigste Unterscheidungsmerkmale
- 2-Step Flash architecture for low cost vs full-flash (vs. MAX1285BCSA (12-bit SAR))
- Integrated sample-and-hold eliminates external S/H (vs. TLC549ID (8-bit SAR, no internal S/H at high rate))
- Single 3.3 V supply matches modern logic rails (vs. PCM4202IDBREP (24-bit audio ADC))
Designhinweise
Decouple VDD with a 0.1 uF X7R ceramic plus a 10 uF tantalum or ceramic bulk capacitor placed within 5 mm of the VDD pin. The XRD87L75AIUTR-F samples at 10 MSPS, so high-frequency switching transients on VDD directly couple into AIN via the internal capacitor network. Split analog VDD and digital VDD with a ferrite bead if the system rail is shared with a noisy digital IC, and place the analog bulk capacitor on the analog side of the bead.
Do not power the XRD87L75AIUTR-F from a 5 V supply; the part is a 3.3 V device and absolute-maximum VDD is below 5 V. The analog input range is 0V-VDD, so even though the input can tolerate 0-3.3 V, applying 5 V to AIN damages the part. If the source signal is 0-5 V, add an external resistor-divider or buffer amplifier with a 3.3 V rail to keep AIN within spec.
Place the input RC anti-alias filter directly at the AIN pin to limit out-of-band noise; a typical first-stage is a 50 ohm series resistor plus a 20 pF capacitor to ground. Route the parallel 8-bit CMOS output bus with matched trace lengths and a series-termination resistor (33-68 ohm) near the ADC to dampen reflections. Keep the analog ground pour solid and stitch it to digital ground only at a single point under the AGND pin to avoid ground-loop noise coupling.
Drive AIN with a low-output-impedance op-amp buffer capable of settling to 0.5 LSB in less than half the clock period at 10 MSPS. The XRD87L75AIUTR-F's switched-capacitor input draws transient current at each clock edge, so a slow op-amp introduces distortion. Recommended: an op-amp with at least 100 MHz GBW and 50 V/us slew rate, such as a current-feedback amplifier for video-bandwidth signals.
Compliance-Informationen
