HI5766KCAZ Overview
An ADC (analog-to-digital converter) is a data converter that transforms a continuous-time analog input voltage into a discrete digital output code, forming the boundary between the analog and digital signal domains. Within the broader product hierarchy, the HI5766 is a high-speed pipelined ADC, a sub-category of Nyquist-rate data converters that achieve fast sample rates through multi-stage pipeline architectures with per-stage residue amplification. Pipelined ADCs sit alongside successive-approximation-register (SAR) and flash ADCs in the data-converter taxonomy, all belonging to the wider class of mixed-signal and data acquisition ICs used in instrumentation, communications, and imaging systems.
Key features of the HI5766KCAZ include a 10-bit resolution, 60 MSPS maximum sampling rate, single +5 V analog supply operation, fully differential analog input for high common-mode rejection, an external reference input, a parallel CMOS digital output bus, and a single analog input channel. The pipelined architecture provides 1 sample per clock cycle of latency, ideal for continuous streaming rather than multiplexed acquisition. According to the Renesas datasheet, the device consumes only 260 mW and maintains good dynamic performance at full conversion speed.
Typical applications include flat-panel display digitizers, set-top box video digitizers, professional video broadcast equipment, IF (intermediate-frequency) sampling for communications receivers, medical ultrasound beamformers, and high-speed instrumentation. The wide analog input bandwidth and low power make the HI5766KCAZ attractive for portable imaging and battery-powered test equipment.
When designing with the HI5766KCAZ, ensure the analog input is AC-coupled or DC-biased within the common-mode range of the differential input, place the reference decoupling capacitor directly at the REFT/REFB pins, and provide a clean low-jitter clock at the encode input to preserve SNR.

Typical Applications
HI5766KCAZ is suitable for 6 applications: Flat-Panel Display Digitizer, Set-Top Box Video Capture, Communications IF Sampling, Medical Ultrasound Beamformer, Industrial Test Instrumentation, Digital Imaging Front-End.
Flat-Panel Display Digitizer
The HI5766KCAZ is well suited for flat-panel display digitizers where analog RGB or component video must be converted to digital pixel streams. Its 60 MSPS sample rate exceeds 27 MHz SD video and supports up to XGA-resolution line-scan digitizers, while the pipelined architecture provides 1-cycle latency for continuous streaming. The 260 mW power dissipation keeps thermal budgets low in compact TFT-LCD monitor assemblies, and the parallel CMOS outputs connect directly to display controllers without level translation.
Recommended
Set-Top Box Video Capture
In set-top box video capture paths, the HI5766KCAZ digitizes baseband NTSC/PAL or component video before MPEG encoding. Its 10-bit resolution preserves broadcast-grade dynamic range, while the fully differential input rejects ground noise between the tuner and digitizer. The 60 MSPS rate supports oversampled decoding for comb-filter 3D-Y/C separation, and the parallel CMOS bus feeds downstream encoders without serializer overhead. Power consumption of only 260 mW allows fanless set-top designs.
Recommended
Communications IF Sampling
The HI5766KCAZ performs intermediate-frequency (IF) sampling in digital radios and cellular base-station receivers. Its wide analog input bandwidth allows direct IF sub-sampling at tens of MHz, eliminating a downconversion mixer stage. The pipelined architecture maintains 10-bit dynamic performance through the IF range, and the CMOS outputs integrate directly with FPGA or ASIC baseband processors. Low 260 mW power is especially valuable in dense multi-channel receiver cards.
Recommended
Medical Ultrasound Beamformer
Portable medical ultrasound systems use the HI5766KCAZ to digitize time-gain-amplified echo signals with 10-bit resolution at 60 MSPS per channel. The fully differential input rejects common-mode noise from adjacent channel electronics, while the pipelined 1-cycle latency supports real-time beamformer datapaths. The 28-SSOP package and 260 mW power are critical for multi-channel probe designs where PCB area and thermal headroom are constrained by the handheld form factor.
Recommended
Industrial Test Instrumentation
In bench-top oscilloscope plug-ins, data-acquisition boards, and ATE (automatic test equipment), the HI5766KCAZ functions as a high-bandwidth digitizer for transient and repetitive signals. Its 60 MSPS rate captures up to 30 MHz of single-shot analog bandwidth, while parallel CMOS outputs integrate with FPGA-based capture memory. The commercial temperature range -40C to +85C supports laboratory and light-industrial environments, and SSOP-28 allows easy rework on prototype boards.
Recommended
Digital Imaging Front-End
The HI5766KCAZ digitizes the analog output of CCD or CMOS image sensors in line-scan and area-scan industrial cameras. The differential input rejects switching noise from pixel clock drivers, and the 60 MSPS rate matches 1080p progressive scan formats without decimation. The pipelined architecture provides deterministic pixel-to-pixel latency essential for machine-vision alignment, while the 260 mW power keeps total camera-board dissipation well within sealed-housing budgets for factory-floor installations.

Key Differentiators
- Highest sample rate in 28-SSOP 10-bit ADC class (vs AD9200JRSZ)
- Differential input supports higher SNR than single-ended (vs ADS901E/1KG4)
- Renesas/Intersil lineage with mature tooling (vs Generic SSOP-28 ADC)
Design Notes
Estimated: Place the REFT and REFB bypass capacitors within 100 mil of the IC pins to minimize reference ladder kickback. Route the analog +5 V supply through a ferrite bead from the digital +5 V supply to prevent switching noise coupling into the analog comparator stages. Use a solid ground plane on layer 2 with vias stitching both analog and digital ground returns under the SSOP-28 footprint.
The encode clock input is sensitive to jitter: estimated SNR degradation is 1 dB per 1 ps RMS jitter at 60 MSPS. Use a low-jitter clock source (TCXO or clean FPGA PLL) and route the encode trace as a 50 ohm matched transmission line keeping skew between encode and analog input minimal. DNL and INL specified in the datasheet assume ideal clocking.
Estimated: Total 5 V supply current at 60 MSPS is approximately 52 mA (260 mW). Provide a regulator with at least 100 mA headroom and decouple analog and digital rails separately at the device. Place a 10 uF tantalum and 0.1 uF ceramic bypass on each supply pin pair. Power-on sequencing is not strictly required since analog and digital rails share the same +5 V supply.
Do not leave the differential analog input floating - the common-mode voltage must be established by external biasing to mid-supply if single-ended drive is used. Exceeding the absolute maximum analog input range can permanently damage the input ESD structures. The REFT/REFB capacitors must be low-ESR ceramic; tantalum or electrolytic capacitors degrade AC performance significantly.
