CD74HC138

CD74HC138 - 3-to-8 Line Decoder/Demux 2-6V | Texas Instruments

The Texas Instruments CD74HC138 is a high-speed silicon-gate CMOS 3-to-8 line decoder/demultiplexer with inverting outputs, supplied in a 16-pin package (PDIP, SOIC, and other variants), operating from a 2V to 6V supply with three binary select inputs and eight active-low outputs. According to the TI datasheet SCHS147J, the device is well suited to memory address decoding or data routing applications. A decoder/demultiplexer is a combinational logic device in the broader logic IC family (logic -> decoder -> demultiplexer -> data routing IC). Decoders convert binary-coded inputs into one-hot outputs, while the same circuit used with enables asserted acts as a demultiplexer routing data to one of eight output lines. The CD74HC138 belongs to TI's High Speed CMOS (HC) logic family, offering CMOS low power with LSTTL-comparable speed. Key features include three binary select inputs (A0, A1, A2) with full on-chip decoding, three enable inputs (two active-low, one active-high) supporting cascaded 4-to-16 or larger decoders without external gates, eight active-low outputs suited to memory chip-select (CS) and enable lines, low quiescent CMOS power consumption, and wide 2V to 6V supply operation typical of the HC family. Architecturally, the CD74HC138 uses high-speed silicon-gate CMOS construction with speeds comparable to low-power Schottky TTL logic. When used as a demultiplexer, the active-low enables serve as the data input while the select inputs route the data to the addressed output, eliminating external inverter gates. Typical applications include memory address decoding for SRAM/EPROM/Flash chip selects, I/O port expansion in microprocessor systems, data routing and demultiplexing, and address latching in embedded control systems. Its inverting outputs directly drive active-low memory CS/CE inputs without external inverters. Design tip: tie unused enable inputs to their inactive levels and keep select lines short; for 4-to-16 decoding, cascade two devices using one enable as the MSB select.

CD74HC374

CD74HC374 - Octal D Flip-Flop, 3-State, 2-6V | Texas Instruments

The Texas Instruments CD74HC374 is a high-speed CMOS logic octal positive-edge-triggered D-type flip-flop with 3-state outputs, housed in a 20-pin package (PDIP-20 (N), SOIC-20 (DW), or TSSOP-20 (PW)). It operates from a wide 2V to 6V supply and each output can drive up to 15 LSTTL loads, making it a robust bus-oriented storage element. An octal D-type flip-flop is a sequential logic IC containing eight independent D flip-flops that share a common clock and output-enable control. It belongs to the 74HC (High-speed CMOS) logic family, which combines LSTTL-compatible speed with the low static power consumption of CMOS technology, sitting within the broader hierarchy of digital logic ICs > flip-flops > edge-triggered registers. Key features include positive-edge-triggered data capture on the LOW-to-HIGH clock (CP) transition, 3-state outputs controlled by an active-low output enable (OE) that is independent of register operation, a typical propagation delay of 15 ns at 5V, and a maximum clock frequency of 30 MHz. The silicon-gate CMOS process provides high noise immunity and very low quiescent current compared with bipolar LSTTL equivalents. Architecturally, data present on the D inputs is stored on each rising clock edge, while OE=HIGH forces all Q outputs into a high-impedance state without disturbing the stored register contents. This enables bus multiplexing, shared data buses, and bidirectional data flow in microprocessor and memory systems. The device works in both 3.3V and 5V logic systems thanks to its wide supply range. Typical applications include microprocessor address and data latching, I/O port expansion, bus interfacing, register files, and synchronization stages in DSP and communication interfaces. Designers should keep the clock clean and glitch-free, control OE to avoid bus contention, and place 100 nF decoupling capacitors close to the VCC pin. According to TI datasheet SCHS183A, unused inputs must never be left floating.

CD74HC4511M96 - CMOS BCD-to-7-Segment Decoder/Driver SOIC-16 | TI

The Texas Instruments CD74HC4511M96 is a High Speed CMOS Logic BCD-to-7-Segment Latch/Decoder/Driver supplied in a 16-pin SOIC (D) package on tape and reel (M96 suffix). It operates over a 2 V to 6 V VCC range for the HC version, decodes four BCD address inputs (D0-D3) into seven segment outputs (a-g) plus ripple blanking, and integrates input latches, lamp-test (LT), and active-low blanking (BL) control inputs. Per the TI product page, the part delivers 10 mA source current per segment at 6 V on the HC variant, sufficient to directly drive common-cathode LED displays with external current-limiting resistors. A BCD-to-7-segment decoder is a logic IC that converts a 4-bit Binary Coded Decimal input (0-9) into the seven individual segment drive signals (a, b, c, d, e, f, g) needed to display a decimal digit on a 7-segment LED or LCD display. These devices sit in the logic IC hierarchy: decoder/driver -> display driver -> logic IC -> integrated circuit -> semiconductor. They are essential building blocks in numeric displays used in instrumentation, appliance panels, industrial counters, and embedded systems where a microcontroller must drive multi-digit readouts efficiently. Key features of the CD74HC4511M96 include input latches for BCD code storage, allowing data to be held stable while multiplexing multiple digits; lamp-test and blanking capability for testing all segments simultaneously and for PWM-based dimming; balanced propagation delays and transition times; and significant power reduction versus the original CD4000-series CMOS designs. The high-output sourcing capability (10 mA at 6 V) eliminates the need for external segment drivers in most LED display applications. The CD74HC4511M96 uses CMOS technology with CMOS-compatible inputs on the HC variant. Its 16-pin SOIC (D) small-outline surface-mount package measures approximately 9.9 mm x 3.9 mm with a 1.27 mm pin pitch, making it well-suited to compact PCB layouts. The integrated latch enables display multiplexing with no external storage, simplifying firmware and reducing microcontroller pin count when several digits share a data bus. Typical applications include digital panel meters, instrument counters, industrial control readouts, appliance displays (microwave ovens, washing machines), electronic scoreboards, point-of-sale terminals, and any embedded system that needs to display decimal digits on a 7-segment LED or LCD. Designers use it when they need a hardware decoder to offload display refresh from a microcontroller or when supporting multi-digit multiplexing without continuous MCU intervention. When designing with this device, add series resistors between each segment output and the LED anodes to limit current, or use a constant-current driver if brightness uniformity is critical. For multi-digit multiplexing, route BL through a PWM signal or high-frequency oscillator to achieve dimming and ghosting reduction. The LE (Latch Enable) input must be low for transparent operation and high to store the BCD code. The 'M96' suffix indicates tape-and-reel packaging for high-volume assembly. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found on any single distributor listing, giving engineers a one-stop reference for selecting and using the CD74HC4511M96 in new designs and as a drop-in replacement.

CD74HCT165M96

CD74HCT165M96 - 8-Bit Parallel-In/Serial-Out Shift Register | TI

The Texas Instruments CD74HCT165M96 is an 8-bit parallel-in/serial-out shift register built on High-Speed CMOS (HCT) logic, housed in a 16-pin SOIC (D) package with a -55C to +125C operating temperature range. It provides complementary serial outputs (Q7 and Q7-bar) from the last stage, asynchronous parallel load via an active-low PL pin, and TTL-compatible inputs that interface directly with 5V CMOS or bipolar TTL logic rails. The wide operating temperature grade supports both commercial and military-grade designs in a single BOM line. What is a parallel-in/serial-out shift register? A shift register is a sequential logic block that stores and shifts multi-bit data along a chain of flip-flops on each clock edge. A parallel-in/serial-out (PISO) variant accepts 8 bits in parallel, then clocks them out one bit at a time over a serial line. Within the broader IC taxonomy, PISO registers sit under the Logic IC family -> Shift Registers -> PISO registers, and they are the building block of which microcontroller peripherals (UART, SPI) are typically constructed. PISO devices are used to reduce the I/O count on a host MCU by converting parallel button or sensor data into a single-wire serial stream. The CD74HCT165M96 features buffered inputs, complementary Q7/Q7-bar outputs, asynchronous parallel load, and a wide fanout of 10 LSTTL loads on standard outputs and 15 LSTTL loads on bus-driver outputs. The asynchronous load (active-low PL) lets the system load parallel data without waiting for a clock edge, which is critical when capturing fast events. Complementary outputs enable easy wire-OR or polarity-inversion without an external inverter. Architecturally, the CD74HCT165 uses HCT-CMOS silicon gates, which deliver CMOS-style low static power (typically microampere quiescent supply current) while presenting TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V). The serial data path is implemented as 8 master-slave D flip-flops clocked by the rising edge of the CLK input, with the DS serial data input multiplexed through the PL-controlled input gate. The HCT family operates from a single 4.5 V to 5.5 V supply. Typical applications include scanning a matrix of front-panel push-button switches, multiplexing 8 lines of digital sensor data into a single microcontroller UART, expanding GPIO on low-pin-count MCUs, industrial control front-ends, and keyboard/mouse matrix scanners. In each case the part reduces host-side pin count and PCB routing complexity by converting parallel inputs to a single serial bit stream. When designing with this device, keep trace lengths short between parallel data sources and the D0-D7 inputs to minimize skew, and route the CLK and PL signals with a ground return to avoid transient capture errors. Power-supply decoupling of 0.1 uF next to VCC is recommended for noise-sensitive designs.

CDC3RL02BYFPR - 52MHz 1:2 Low Phase-Noise Clock Buffer | TI

The Texas Instruments CDC3RL02BYFPR is a dual-channel square/sine-to-square wave clock fan-out buffer that accepts a single clock source and distributes it to two outputs with minimal additive phase noise, supplied in an 8-pin XFBGA/DSBGA (YFP) package. According to the TI CDC3RL02 datasheet, the device operates up to 52 MHz and is specifically designed for portable end-equipment such as mobile phones, where clock buffering with minimal additive phase noise and fan-out capabilities is required. A clock fan-out buffer is a clock-distribution integrated circuit that takes one reference clock signal and replicates it across multiple outputs while preserving timing integrity. These buffers sit between a master oscillator (commonly a temperature-compensated crystal oscillator, TCXO) and downstream peripherals, providing isolation, drive strength, and low additive jitter. Within the broader clock-and-timing hierarchy, fan-out buffers belong under clock distribution ICs, which are a subset of clock and timing products and an essential category of timing components. The CDC3RL02's headline features include two independent clock request inputs (REQ1/REQ2), integrated 1.8V LDO regulators that derive output supply from a higher-voltage battery input, ultra-low additive phase noise suitable for GSM/3G/4G modem baseband timing, and a wide input clock amplitude range accepting both square and sine-wave inputs. Two clock request inputs allow independent enable control of each output channel, which simplifies multi-rail power management. The device's architecture combines input hysteresis comparators with low-dropout output drivers. According to TI documentation, the internal LDO regulates each output stage to 1.8V from a battery input up to ~3.6V, eliminating the need for an external low-voltage rail. Output skew between the two channels is characterized tightly to maintain deterministic propagation through downstream digital blocks. Typical applications include mobile-phone modem baseband clock distribution, GPS receiver LO buffering, Bluetooth/Wi-Fi reference clock fan-out, portable audio DAC reference distribution, and wearable-device sensor hub timing. Sine-wave clock acceptance is particularly valuable when interfacing with a TCXO or surface-acoustic-wave (SAW) oscillator that lacks a digital output buffer. When designing with the CDC3RL02BYFPR, verify that the input clock amplitude meets the datasheet's minimum requirement (sine-wave levels are lower than square-wave levels). Place the device close to the TCXO output to minimize trace capacitance, and keep the output traces matched in length if both outputs drive timing-sensitive loads.

It is part of the CDK1308 family which scales sample rate across 20/40/65/80 MSPS variants, allowing system designers to select the bandwidth that matches their signal chain. As of 2026-10-13, the part is in production and available through authorized distributors including Mouser, Octopart-listed stockists, and MaxLinear franchised partners. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time, continuous-amplitude analog signals into discrete-time, discrete-amplitude digital codes. The CDK1308 family sits in the precision data-converter category, a sub-family of signal-chain data acquisition ICs that bridge analog sensors and digital processors. Within the broader IC hierarchy: ADC -> data converter -> data acquisition IC -> mixed-signal IC -> semiconductor. Successive-approximation (SAR) and pipelined architectures dominate the 1-80 MSPS tier where the CDK1308 competes, with power consumption, channel count, and SNR/ENOB being the primary differentiators.

The device employs digital error correction to mitigate pipeline-stage linearity errors, and a proprietary internal reference that eliminates the need for an external reference IC in most designs. The combination of internal reference, small QFN package, and low quiescent power makes the part attractive for portable, space-constrained designs. Typical applications for the CDK1308AILP40 include portable test and measurement equipment, USB oscilloscope front ends, medical imaging signal conditioning, and mid-bandwidth industrial instrumentation. Designers choose this part when 10-bit resolution is sufficient and the primary design constraint is power budget rather than absolute noise performance. Compared with 12/14-bit alternatives, the 10-bit architecture trades dynamic range for substantially lower power and smaller die area, which translates directly into battery run-time and PCB footprint. When designing with the CDK1308AILP40, route the analog inputs with guarded differential pairs and decouple AVDD/DRVDD with separate 1uF and 0.1uF ceramic capacitors placed as close as possible to the supply pins. The PD_N (power-down) and SLP_N (sleep) pins can be used for duty-cycled operation in battery-powered designs. Drive the analog input with a low-impedance, low-noise op-amp front end, and ensure the clock source is a low-jitter LVCMOS or LVPECL driver to avoid degrading SNR.

CDK1308BILP40 - 10-bit 40MSPS Ultra-Low Power ADC | MaxLinear

The MaxLinear (formerly Exar Corporation) CDK1308BILP40 is a 10-bit, 40 MSPS ultra-low-power analog-to-digital converter (ADC) housed in a 40-pin QFN package (LP40). The CDK1308 family is offered in four speed grades (20/40/65/80 MSPS), and the BILP40 suffix denotes the 40 MSPS speed grade with industrial temperature range. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time, continuous-amplitude analog signals into discrete digital codes. Within the broader signal chain hierarchy, ADCs sit between analog front-end conditioning (amplifiers, anti-alias filters) and digital processing (FPGA, microcontroller, DSP), making them a critical component in data acquisition systems, imaging, and communications equipment. Ultra-low-power ADCs such as the CDK1308 target portable and battery-powered applications where milliwatts-per-sample directly impact battery life and thermal budgets. Key features include 25 mW typical power dissipation at 40 MSPS, 61.6 dB SNR at an 8 MHz analog input, internal reference circuitry (eliminating external reference components), a 1.8 V analog core supply, and a separate 1.7 V to 3.6 V digital I/O supply for flexible host interfacing. The device uses a proprietary CMOS architecture with digital error correction, delivering high linearity while keeping die area and power low. Parallel CMOS outputs simplify connection to FPGAs, ASICs, and microcontrollers without requiring an external serializer. The CDK1308B is pin-compatible with the CDK1307 family, enabling system scalability between 10-bit (CDK1308) and 12-bit (CDK1307) resolutions on the same PCB. This makes the part attractive for medical imaging, portable test equipment, digital oscilloscopes, and IF communications designs where a single hardware platform must support multiple performance tiers. Typical applications span handheld ultrasound front-ends, digital oscilloscopes, IF sampling for software-defined radio (SDR), and portable industrial inspection cameras. The combination of low power, small QFN footprint, and internal reference simplifies multi-channel designs where board area and BOM cost are constrained. When designing with the CDK1308BILP40, decouple AVDD and DVDD separately with 1 µF and 100 nF capacitors placed as close to the pins as possible. Drive the analog input through a wideband op-amp or transformer; the input is a switched-capacitor structure that benefits from a low-impedance source to preserve SNR at high input frequencies.

According to the MaxLinear datasheet (Rev 1B), the CDK1308C dissipates only 38 mW at 65 MSPS, making it one of the lowest-power 10-bit pipeline ADCs in its speed class. An analog-to-digital converter (ADC) is a semiconductor device that converts real-world continuous analog signals into discrete digital codes for processing by microcontrollers, FPGAs, or DSPs. Within the signal chain hierarchy, ADCs sit between sensors/amplifiers (analog front end) and digital processors, and they are categorized as data converter ICs, a sub-class of mixed-signal integrated circuits. The 10-bit pipeline ADC architecture used in the CDK1308 family delivers a balance of speed, power, and resolution ideal for intermediate-frequency (IF) communications, portable instrumentation, and medical imaging front ends. Key features of the CDK1308CILP40 include 61.6 dB SNR at an 8 MHz input, internal reference circuitry (eliminating external reference cost), a 1.8 V analog core supply, and a 1.7 V to 3.6 V digital I/O supply that interfaces directly to 1.8 V, 2.5 V, or 3.3 V logic families. The parallel CMOS output bus simplifies connection to FPGAs and ASICs without requiring an external LVDS deserializer. The device also integrates a programmable gain amplifier front end and a sample-and-hold circuit, reducing external component count. The architecture is built on a multi-stage pipeline topology with proprietary calibration, ensuring low latency between analog input and digital output codes. Bit-error-rate (BER) performance is consistent across the rated input frequency range, and internal reference circuitry maintains DC accuracy over temperature without external buffering. Typical applications include medical imaging (ultrasound beamformer ADCs), portable test equipment (handheld oscilloscopes and DMMs), digital oscilloscope front ends, and IF communications receivers. Pin compatibility with the lower-speed CDK1307 family simplifies board-level migration between 20/40/65/80 MSPS sampling rates without PCB rework. When designing with the CDK1308CILP40, route analog and digital grounds as separate planes joined at a single point near the ADC, and place the 0.1 µF decoupling capacitors within 2 mm of each supply pin. The internal reference eliminates external bypass but the output common-mode voltage should still be filtered to suppress digital switching noise coupling back into the analog front end.

CDK2307BILP64 - Dual 12/13-bit 40MSPS ADC | MaxLinear/Exar

The MaxLinear (formerly Exar/Cadeka) CDK2307BILP64 is a dual-channel, 12/13-bit pipelined analog-to-digital converter (ADC) sampling at up to 40 MSPS, housed in a 64-pin QFN-EP (9x9 mm) package. It integrates two independent ADC channels with internal reference circuitry, a CMOS control interface, and CMOS output data, delivering high performance for multi-channel data acquisition systems while keeping system power and footprint low. What is a pipelined ADC? A pipelined analog-to-digital converter is a multi-stage switched-capacitor architecture that samples and quantizes analog input signals through cascaded low-resolution stages, with each stage driving the residue into the next. Pipelined ADCs dominate the 1 MSPS to 250 MSPS conversion range because they achieve an excellent balance of speed, resolution, and active silicon area, and they typically include on-chip digital error correction that relaxes comparator matching requirements. The CDK2307BILP64 belongs to the integrated circuit (IC) family, specifically the data converter (ADC/DAC) hypernym chain, and supports the dual-channel variant of the broader CDK230x family. Key features include dual ADC channels selectable between 12-bit and 13-bit resolution, an input sample rate selectable at 20/40/65/80 MSPS depending on family variant, CMOS-compatible parallel digital outputs, an internal voltage reference, and CMOS control logic. Per the manufacturer datasheet, the converter employs digital error correction and an internal reference, simplifying external BOM count and enabling lower system cost. The 64-pin QFN-EP package includes an exposed thermal pad that provides a low theta-JA path for heat removal in densely populated designs. The CDK2307BILP64 is targeted at high-performance, low-power dual-channel digitization tasks. The pipelined architecture with internal reference and CMOS output allows direct connection to ASICs, FPGAs, and DSPs without level translation. Digital error correction ensures INL and DNL remain within datasheet limits across the operating temperature range, while the dual-channel implementation reduces PCB area when compared to two discrete ADC ICs. Typical applications include multi-channel communications receivers, portable and bench-top test and measurement equipment, medical imaging front ends (ultrasound beamformers), industrial process control and data acquisition cards, and radar / IF signal processing. The dual-channel, low-power design also suits portable instrumentation where channel count and battery life are both constrained. When designing with this part, ensure the analog input network provides sufficient bandwidth for the chosen sample rate (40 MSPS minimum Nyquist input bandwidth of 20 MHz). Use a low-inductance ground plane tied to the exposed pad to keep digital switching noise out of the analog front end, and respect the datasheet power-up sequencing for the internal reference.

CDK2307CILP64 - Dual 65MSPS 12/13-bit ADC | MaxLinear

The MaxLinear (formerly Exar / Cadeka) CDK2307CILP64 is a dual-channel, 12/13-bit pipelined Analog-to-Digital Converter (ADC) capable of sampling at 20, 40, 65, or 80 MSPS per channel, housed in a 64-pin QFN (LP64) package with exposed thermal pad. The CDK2307 family provides high-performance, low-power dual ADC operation with internal reference circuitry, CMOS control interface and CMOS output data paths, based on a proprietary pipelined converter architecture with onboard digital error correction. An ADC (Analog-to-Digital Converter) is a data acquisition component that converts real-world analog signals into discrete digital codes for downstream processing by FPGAs, DSPs, microcontrollers, or ASICs. Within the converter hierarchy, the CDK2307CILP64 sits in the pipelined-ADC subcategory, which is the dominant topology for sampling rates between 10 MSPS and 250 MSPS because it balances high input bandwidth and resolution against modest die area and power. Selection between SAR (successive-approximation) and pipelined ADC families is driven primarily by the required sample rate and channel count. Key features include simultaneous dual-channel sampling at up to 80 MSPS, a maximum sample rate of 80 MSPS at 12 bits and 65 MSPS at 13 bits, CMOS-compatible digital I/O, and an internal voltage reference that eliminates external reference components. The wide input common-mode range and low differential nonlinearity (DNL) make the converter well-suited to intermediate-frequency (IF) sampling, multi-carrier base-station receivers, and high-density video / imaging front ends. Power dissipation scales linearly with sample rate, allowing designers to trade speed for power in lower-throughput operating modes. Architecturally, each channel of the CDK2307CILP64 uses a multi-stage pipelined switched-capacitor core followed by digital error-correction logic. The internal reference and clock-receiver blocks are shared between channels, while the analog inputs and digital outputs are independent, allowing simultaneous sampling of two real signals or one I/Q complex signal pair in a baseband or low-IF radio chain. Typical applications include wireless infrastructure (GSM/EDGE/UMTS base-station receiver IF stages), cable-modem / set-top box downstream digitizers, multi-channel test and measurement instruments, ultrasound beamforming front ends, and dual-channel imaging / video capture. The 64-pin QFN exposed-pad package supports surface-mount PCB assembly and provides a low-thermal-resistance path to the PCB copper for heat spreading during sustained high-sample-rate operation. When designing with this part, ensure each analog input is driven from a low-impedance, wideband differential buffer; bandwidth-limiting the analog front end below the Nyquist frequency (half the sample rate) prevents aliasing but must not degrade the aperture-time accuracy. Decouple AVDD and DVDD pins separately at the IC with 100 nF ceramic capacitors to keep the high-frequency switching currents out of the analog ground return.

Each ADC channel integrates internal reference circuitry, CMOS control logic, and CMOS parallel output data, with digital error correction for low residual offset and gain error. Per the manufacturer datasheet, the device operates from a single 1.7 V to 3.6 V analog supply and a separate 1.7 V to 3.6 V digital supply, consuming approximately 102 mW per channel at 80 MSPS. An ADC (Analog-to-Digital Converter) is a data converter that samples continuous analog signals and produces discrete digital codes. Within the data-converter hierarchy, the CDK2307DILP64 sits in the pipelined-ADC subfamily, which is the dominant architecture for sample rates between 5 MSPS and 250 MSPS because it balances high sample rate, moderate resolution, and low power per conversion. Pipelined ADCs are widely used in communications, medical imaging, instrumentation, and defense systems where a multi-MHz analog front-end must be digitized with 10-14 bit effective resolution. Key features of the CDK2307DILP64 include user-selectable 12-bit or 13-bit resolution, four speed grades (20/40/65/80 MSPS) shared across the family, a single-ended analog input, parallel CMOS output bus, and an internal bandgap reference. The dual-channel integration saves board area versus two discrete ADCs while maintaining channel-to-channel matching for time-interleaved or I/Q demodulation architectures. The 64-pin QFN package exposes a thermal pad, supporting the ~200 mW total dissipation without requiring an external heatsink. The pipelined core uses a multi-stage switched-capacitor architecture with per-stage MDAC gain of 2 and digital error correction, yielding low DNL and INL. The internal reference simplifies BOM cost, while a separate REFIN pin allows the user to drive an external reference for gain calibration or ratio-metric measurements. The CMOS output bus reduces digital switching noise on the supply rails, easing layout in mixed-signal designs. Typical applications include communications I/Q baseband digitization, multi-channel data acquisition cards, medical ultrasound beamformers, handheld test instrumentation, and industrial inspection imaging. Its dual channels suit diversity receivers, simultaneous-sample vibration analysis, and any design where PCB area or channel-to-channel skew is critical. When designing with this part, place the analog and digital supplies on separate PCB planes joined at a single ferrite bead near the IC, and bypass each supply pin with a 100 nF X7R capacitor within 2 mm of the pad. Use the exposed pad as the primary thermal and ground return path; failing to solder it degrades electrical and thermal performance.

It integrates two independent ADC channels, each preceded by a highly linear Track-and-Hold Amplifier (THA) optimized for input frequencies up to several hundred MHz, and it consumes 78 mW per channel at 80 MSPS. The device accepts single-ended analog inputs and is designed for low-power, high-dynamic-performance applications such as imaging, communications baseband, and portable instrumentation. An ADC (Analog-to-Digital Converter) is a data conversion integrated circuit that transforms continuous-time analog signals into discrete digital codes at a specified sampling rate, forming the critical bridge between the analog front end and the digital signal processing domain in mixed-signal systems. ADCs are classified by resolution (8/10/12/14/16-bit), sampling rate (kSPS to GSPS), and architecture (SAR, pipeline, sigma-delta, flash); the CDK2308 is a low-power pipeline ADC optimized for IF/RF baseband and video bandwidths. Key features of the CDK2308DILP64 include dual 10-bit resolution, programmable sample rates (20/40/65/80 MSPS), 78 mW power dissipation per channel at full speed, several independent power-down modes (channel standby, chip standby, full power-down) for battery-friendly operation, and a fast startup time that lets the converter leave idle mode with minimal latency. The 64-QFN package offers excellent thermal performance and a small 9x9 mm PCB footprint suitable for dense multi-channel receiver designs. The CDK2308DILP64 uses a pipelined architecture with internal reference and proprietary input THA design. Each channel can be independently powered down while the partner channel remains active, allowing asymmetric duty cycling in time-multiplexed systems. The wide input bandwidth and low aperture jitter make the part well suited to undersampling IF signals in software-defined radio and to digitizing CCD/CIS outputs in industrial camera front-ends. Typical applications include communications IF/baseband digitizers, set-top box and cable modem tuners, portable/low-power imaging systems, CCD/CIS sensor front-ends, and general-purpose high-speed data acquisition. In imaging, the dual-channel architecture can directly digitize RGB or stereo video streams without an external mux. When designing with the CDK2308DILP64, place the analog input traces as matched 50-ohm (or 75-ohm) controlled-impedance lines, keep the analog and digital ground returns separated until they join at the exposed pad, and provide a low-noise, low-dropout LDO for AVDD to preserve SNR. A 0.1 uF X7R bypass cap placed within 3 mm of each supply pin is essential.

CDK2308DITQ64X

CDK2308DITQ64X - Dual 10-bit ADC, 80MSPS, TQFP-64 | MaxLinear

The MaxLinear CDK2308DITQ64X is a dual 10-bit analog-to-digital converter supporting 20/40/65/80 MSPS sampling rates, housed in a 64-pin TQFP package. The device integrates two ADC channels with internal reference circuitry, a CMOS control interface, and CMOS output data, all based on a proprietary architecture. The converters operate from a single 3.3 V supply and consume low power, making them well-suited for portable and high-density multi-channel data acquisition systems. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time analog voltage or current signals into discrete digital codes at a defined sampling rate. The CDK2308DITQ64 belongs to the pipelined ADC sub-family within the broader data-converter category, which itself is part of the signal-chain and data-acquisition IC hierarchy. Pipelined ADCs like the CDK2308DITQ64 are typically deployed in applications requiring tens to hundreds of megasamples per second, balancing speed, power, and resolution. Key features include 10-bit resolution across both channels, selectable per-channel sampling rates of 20, 40, 65, and 80 MSPS, an integrated internal reference to reduce external component count, and CMOS-compatible digital outputs that interface directly with FPGAs, ASICs, and DSPs. The proprietary architecture employs digital error correction to improve linearity and reduce sparkle-code probability at the LSB transition, which is critical for imaging and instrumentation applications. Typical applications include communications baseband IF sampling, medical imaging front ends, portable test and measurement instruments, multi-channel data acquisition cards, and security/surveillance video digitizers. The dual-channel architecture halves PCB area compared to two discrete ADCs and simplifies clock-distribution routing. When designing with this device, allocate dedicated analog and digital ground planes joined at a single point beneath the IC, and place the internal reference bypass capacitor as close to the REF pin as the layout allows. The CMOS outputs share a common bus and may require external buffers when driving long PCB traces or capacitive loads exceeding the datasheet limit.
