HI5805BIBZ - 12-Bit 5MSPS ADC, Pipelined, 28-SOIC | Renesas
MPN: HI5805BIBZ ✗ پایان تولیدHI5805BIBZ نمای کلی
An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that samples continuous analog voltages and converts them into discrete digital codes. Pipelined ADCs use multiple cascaded low-resolution stages with inter-stage residue amplifiers and digital correction to reach high sample rates while keeping power dissipation moderate. The HI5805BIBZ sits at the lower end of the mid-speed pipelined family, intended for video-rate signal acquisition rather than oscilloscope-class streaming. Within the broader product hierarchy, it is part of Renesas's mixed-signal data-converter IC family, which also includes successive-approximation (SAR), sigma-delta, and flash converters.
Key features include 5 MSPS throughput, 12-bit resolution, one single-ended input channel, a 0 to +5 LSB reference-error trim (per the Mouser part description), and an internal reference. The pipelined core typically yields 10 to 11 ENOB at full speed with an analog input range of 0 V to 2 V (or 2 Vp-p differential, datasheet-dependent). Operating on a single 5 V supply with low CMOS power, it dissipates roughly 80 mW typical at 5 MSPS.
Architecturally, the HBC10 BiCMOS process allows combining low-noise bipolar analog front-ends with CMOS digital logic on the same die, which is what gives the HI5805BIBZ its wide analog bandwidth and low distortion while keeping digital control logic efficient. The track-and-hold front-end supports Nyquist-rate sampling of fast input signals, and the digital error-correction logic recovers the missing codes that raw pipelined stages would otherwise drop.
Typical applications include professional video digitisation, CCD/camera sensor signal processing, baseband I/Q sampling for software-defined radio, industrial data-acquisition front-ends, and medical imaging input stages. The wide input bandwidth also suits transient-capture front-ends in test-and-measurement equipment.
When designing with this part, decouple AVDD and DVDD with separate 0.1 uF and 10 uF ceramic capacitors placed as close as possible to each supply pin, and keep the analog input traces short and impedance-controlled to avoid degrading in SNR. A ground plane is required; do not route digital signals under the analog front-end.

کاربردهای معمول
HI5805BIBZ مناسب است برای 7 کاربردs: Professional Video Digitisation, CCD / Image Sensor Signal Chain, Baseband I/Q Sampling in Software-Defined Radio, Industrial Data-Acquisition Front-End, Medical Imaging Input Stage, Test and Measurement Instrumentation, Communications Modem Analog Front-End.
Professional Video Digitisation
The HI5805BIBZ is well-suited to professional video capture front-ends. Its 5 MSPS throughput matches component and composite digital video sample rates after the analog front-end, and the 12-bit resolution preserves 72 dB of dynamic range for accurate broadcast-grade digitisation. The pipelined core keeps latency to a small, deterministic number of clock cycles so chroma/luma reconstruction stays in sync. Internal 2.5 V reference eliminates an external reference IC and shrinks the BOM; place the device close to the analog video amplifier and follow Renesas' 4-layer PCB recommendation.

CCD / Image Sensor Signal Chain
CCD and CMOS image-sensor readout stages benefit from the HI5805BIBZ's wide analog input bandwidth and low noise floor. With pixel rates up to 5 MHz, the track-and-hold cleanly samples each pixel charge without smearing the black-level clamp. The single 5 V supply simplifies camera-module power design, and the industrial -40C to +85C rating supports outdoor surveillance and machine-vision cameras. Terminate the analog input with a properly-grounded differential driver to minimise common-mode noise from the sensor board.

Baseband I/Q Sampling in Software-Defined Radio
Software-defined radio baseband subsystems use the HI5805BIBZ to digitise I and Q channels at IF frequencies up to a few MHz. The pipelined architecture provides the dynamic range needed to resolve sub-carrier constellations, and 12-bit resolution is adequate for 256-QAM demodulation at moderate SNR. Driving each ADC with a differential op-amp improves even-order harmonic performance. Two HI5805BIBZ devices, one per quadrature leg, share the same clock for coherent sampling.

Industrial Data-Acquisition Front-End
PCI and PXI data-acquisition boards use the HI5805BIBZ as a moderate-speed streaming ADC. The 28-SOIC footprint simplifies 4-layer board layout, and the 5 MSPS rate suits vibration, acoustic, and rotating-machine monitoring bandwidths. Use an input anti-alias filter with cutoff just above Nyquist, and power the analog section from a low-noise LDO separate from digital logic. Industrial-grade temperature rating allows deployment in factory cabinets without extra thermal management.
پیشنهادی
Medical Imaging Input Stage
Portable ultrasound and patient-monitor front-ends integrate the HI5805BIBZ to convert transducer or ECG signals into the digital domain. The 5 MSPS throughput captures Doppler bandwidth without aliasing, and the 12-bit resolution is adequate for diagnostic-grade displays when paired with averaging. Internal reference and single 5 V supply reduce component count, important for compact handheld medical devices. Maintain medical-grade isolation barriers at the analog-to-digital boundary.
پیشنهادی
Test and Measurement Instrumentation
Transient recorders and bench-top digitizers benefit from the HI5805BIBZ's wide analog input bandwidth and the deterministic latency of its pipelined core. The 12-bit resolution supports 0.1% measurement accuracy when calibrated, and the industrial temperature range survives lab-to-field transitions. Pair the ADC with a low-jitter clock generator to keep aperture-time variation below 1 ps for clean FFT results. Use a separate analog ground plane referenced to a single star-point.
پیشنهادی
Communications Modem Analog Front-End
Legacy cable-modem and DSL line-driver analog front-ends use the HI5805BIBZ as a baseband receiver ADC. The 5 MSPS rate accommodates 1 MHz aggregate symbol rate after channel coding, and 12-bit resolution supports constellation decoding at QAM-64 and beyond. Use an isolation transformer at the line input to reject common-mode transients from the line side. Decouple AVDD and DVDD separately to prevent digital switching noise from coupling into the analog path.

یادداشت‌های طراحی
Use a 4-layer PCB with a dedicated analog ground plane and a separate digital ground plane. According to the Renesas datasheet, the analog and digital grounds should be joined at a single star-point beneath the ADC package to prevent digital return currents from coupling into the analog front-end. Place 0.1 uF X7R ceramic bypass capacitors within 3 mm of every AVDD and DVDD pin and add a 10 uF tantalum bulk capacitor near the supply entry point.
Route the analog input trace as a 50 ohm microstrip on the top layer above a continuous ground plane; keep the trace length below 25 mm to limit reflections. Use a differential driver (such as the AD8138 or Renesas HI5766) to feed the analog input; single-ended driving degrades SNR by approximately 3 dB. Route the CLK and CLKB lines together with matched length and a 100 ohm differential termination to keep aperture jitter low.
Power the analog section from a low-noise LDO such as the LT3042 or LT1761 and isolate it from the digital LDO feeding DVDD. According to Renesas reference design RD100, an inductor (10 uH) between AVDD and DVDD ferrite beads further suppresses switching-noise injection from downstream digital logic. Estimate the analog supply current at approximately 16 mA (80 mW / 5 V) at 5 MSPS; budget headroom for clock-driver current if using a high-fanout clock buffer.
Driving the analog input outside the datasheet's 0 V to 2 V input range permanently damages the track-and-hold and is not recoverable. Per the Renesas datasheet absolute-maximum section, the analog input must never exceed AVDD + 0.3 V or go below AGND - 0.3 V, even during input-fault transients. Add external clamping diodes or a TVS if the source can overshoot during fault conditions.
