The Texas Instruments ADS802E is a 12-bit, 10-MSPS sampling analog-to-digital converter in a 28-pin SSOP package. It supports single-ended or differential analog inputs, includes an internal reference, and is specified for operation from a single +5 V supply. Its 65 MHz track-and-hold bandwidth enables the device to capture rapidly changing input signals while the 12-bit quantizer provides 4096 digital output codes. The verified product information identifies the ADS802E as a low-power monolithic converter with approximately 250 mW internal-reference power and no missing codes. An ADC is an analog-to-digital converter, a data-acquisition IC that samples a continuous voltage and maps each sample to a numeric code for processing by a microcontroller, DSP, FPGA, or digital system. The ADS802E belongs to the sampling ADC family and includes the analog input, sample-and-hold circuit, quantization function, reference, and digital interface in one device. This integration reduces external circuitry compared with discrete signal chains, while the single +5 V supply simplifies system power architecture. Key verified characteristics include 12-bit resolution, a 10-MSPS sampling rate, single-ended and differential input capability, internal references, and pin compatibility with ADS800/ADS801. The wideband track-and-hold stage is listed at 65 MHz, helping preserve input bandwidth for high-frequency sampling applications. The device is supplied in a 28-SSOP package, and the verified distributor listing describes its industrial temperature grade and gull-wing terminal form. The converter's architecture is intended for instrumentation, communications, industrial control, and embedded measurement systems where a compact, high-speed ADC is useful. Differential operation can help reject common-mode noise when the analog source and receiver share environmental interference. Single-ended operation is useful when the signal source is referenced to the same ground system as the converter. Engineers must still account for analog input range, reference accuracy, source impedance, sampling timing, clock jitter, and digital-interface levels in the complete design. Typical applications include waveform capture, sensor signal conditioning, communications receivers, industrial process monitoring, and embedded data acquisition. Because the input stage is bandwidth-limited by the track-and-hold network, the input signal and amplifier must deliver adequate bandwidth and settling behavior at the selected sampling rate. The ADS802E is not a drop-in substitute for every ADC in the market; the verified pin-compatible ADS800/ADS801 family is the appropriate starting point when package and interface details match. For layout, place input, reference, and ground connections according to the manufacturer datasheet and keep high-speed digital traces away from sensitive analog nodes. Confirm the selected package footprint and pin assignments before PCB release. The verified data does not provide complete pricing, lifecycle, compliance, or all electrical timing details, so those values must be confirmed with the manufacturer or an authorized distributor. This page combines verified manufacturer and distributor product information with package, sourcing, application, and design guidance intended to reduce component-selection risk. It is intended as an engineering reference, not as a substitute for the complete ADS802 datasheet, application notes, or final qualification records.

The ADS803E belongs to the pipelined ADC family and the broader data-converter and signal-processing semiconductor hierarchy. Its single input channel and parallel output interface make it suitable for measurement and signal-acquisition systems that require deterministic sampling rather than a communications-oriented serial interface. Verified features include 82 dB SFDR at Nyquist, 69 dB SNR, 115 mW low power, and 0.25-LSB low differential nonlinearity. The device also includes internal-reference capability, a flexible input range, and an over-range indicator. These features help simplify calibration and signal conditioning when the source can be scaled to the selected input range. The internal reference can be programmed for a 2 Vpp input range for improved spurious performance and easier source drive, as stated in the verified Texas Instruments description. The ADS803E uses a pipelined conversion architecture to support 5 MSPS sampling while maintaining 12-bit output resolution. Its parallel digital output requires careful routing on a mixed-signal PCB, while the analog input and reference network must be kept away from high-current digital return paths. Designers should pay particular attention to input settling time, reference noise, clock jitter, output timing, and the distinction between signal bandwidth and Nyquist-limited performance. Typical applications include IF and baseband digitization, CCD imaging scanners, and test instrumentation. These uses benefit from the ADC's flexible input range, over-range indication, and sampling capability, provided that the downstream processing bandwidth matches the selected sample rate. The 28-SSOP package is useful for conventional surface-mount assembly but requires adequate pin escape routing and thermal consideration. When designing around the ADS803E, begin by defining the analog signal range and reference arrangement, then verify that the driver can settle within the acquisition interval at 5 MSPS. Use short, controlled traces for the analog input and reference, provide a stable clock, and route digital outputs away from sensitive analog nodes. This page consolidates the verified product identity, distributor listing, datasheet references, application positioning, and replacement constraints.

This pipeline architecture enables high throughput (MSPS-class) at moderate die area, making pipelined ADCs the workhorse of high-speed data acquisition, communications, video, medical imaging, and test instrumentation. The ADS803E/1KG4 sits in the broader hierarchy of: ADC -> data converter -> signal chain IC -> semiconductor. Key differentiating specifications include a programmable 2 Vp-p or 5 Vp-p input range, internal or external reference option, TTL/CMOS-compatible digital outputs, and differential linearity that supports demanding imaging applications. Digital error-correction techniques ensure excellent DNL (differential non-linearity), while the low distortion and high SNR provide the extra margin needed for communications and video signal chains. The ADS803E/1KG4 architecture uses a multi-stage switched-capacitor pipeline with digital error correction, achieving true 12-bit performance at 5 MSPS without the latency penalty of successive-approximation (SAR) ADCs. Its single +5V analog supply simplifies power-tree design versus split-rail converters, and the differential analog input rejects common-mode noise from upstream sensor or driver stages. Typical applications include medical imaging front-ends, communications baseband IF sampling, CCD/CMOS image sensor digitizers, video digitizing, and test-and-measurement instrumentation where 12-bit resolution at 5 MSPS is sufficient. The 28-SSOP footprint is also a near-universal upgrade path to the ADS804 (10 MSPS) and ADS805 (20 MSPS) for future-proof designs. When designing with this converter, ensure the analog input common-mode voltage stays within the specified range, place a small RC anti-aliasing filter at AINP/AINN, and decouple AVDD and DVDD with separate 0.1 uF + 10 uF ceramic capacitors close to the pins. The internal reference eliminates an external reference IC in cost-sensitive designs; for best DC accuracy use an external 2.500V reference. According to TI, the digital outputs can drive TTL and CMOS loads directly without external buffers below 5 pF.

Its 12-bit resolution provides 4,096 code levels, while its 10-MSPS sampling rate supports high-speed waveform capture, IF and baseband digitization, CCD imaging, scanner systems, and test instrumentation. Key performance characteristics combine 10-MSPS throughput with 12-bit resolution, 80-dB Nyquist SFDR, and 69-dB SNR. The flexible input range is useful when the source signal amplitude is not fixed, and the overrange indicator provides a way to detect conditions beyond the nominal conversion range. The ±0.3-LSB differential nonlinearity figure indicates that code-width variation is tightly controlled for precision acquisition and signal-fidelity requirements. The ADS804U uses a parallel interface rather than a serial data interface. This architecture is appropriate when downstream logic can capture many output bits at each conversion event. Designers should account for timing between the sample clock, output data, and downstream logic, and should use controlled-impedance routing where digital transition activity could affect analog signal integrity. The 28-pin SOIC package provides a conventional surface-mount footprint but requires careful handling and layout because the analog input, reference connections, clock, and parallel outputs are all present in one package. Typical applications include IF and baseband digitization, CCD imaging, scanners, communications receivers, and general-purpose test equipment. The 10-MSPS rate is especially relevant to intermediate-frequency or baseband sampling where a compact parallel ADC can feed a DSP, FPGA, or digital capture system. Compared with lower-speed converters, the ADS804U trades higher sampling throughput for greater PCB and timing complexity. The most important design consideration is the analog and digital partitioning around the converter. Place input and reference components close to their associated pins, route the analog input away from high-current clock and parallel-output paths, and define the return-current path continuously. Check the manufacturer datasheet for the exact pin names, reference arrangement, timing specifications, and recommended application circuit before releasing a PCB layout. This product page consolidates verified family specifications, package information, application guidance, and design considerations for engineers evaluating the ADS804U. Distributor inventory, exact pricing, lifecycle detail, and every complete electrical characteristic should be reconfirmed from the current manufacturer and distributor records before procurement or design sign-off.

The ADS805 architecture combines a high-bandwidth track-and-hold circuit with pipelined stages. The high-bandwidth track-and-hold minimizes acquisition-time effects, while low jitter and linear sampling behavior help preserve signal fidelity. The flexible input range allows the system designer to trade signal amplitude against dynamic range and gain requirements. The ADC should be paired with a clean analog supply, a suitable clock source, input protection, and filtering matched to the intended bandwidth. Typical applications include studio cameras, IF and baseband digitization, copiers, communications receivers, video signal acquisition, and test instrumentation. In each case, the 20-MSPS rate allows sampling above the signal bandwidth, while the 12-bit code width and reported dynamic performance provide a practical balance between resolution, speed, and integration complexity. The ADS805E is particularly suitable when the existing board already expects the 28-pin SSOP footprint and the associated pin-compatible family arrangement. Designers should verify the exact package, pinout, reference configuration, input range, and timing requirements against the manufacturer datasheet before layout release. Pay attention to analog input bandwidth, settling time, clock jitter, reference noise, and output interface implementation. The most important design trade-off is ensuring that the input driver and external network do not degrade the converter's measured noise and spurious-free dynamic-range performance. This page consolidates the verified ADS805E product identity, distributor listings, manufacturer family data, pin-compatibility evidence, and practical application guidance. It is designed to help engineers evaluate the converter for procurement and board-level design without treating unsupported specifications as confirmed facts.
ADS805E/1KG4 - 12-Bit 20 MSPS ADC | Texas Instruments | 28-SSOP
The Texas Instruments ADS805E/1KG4 is a 12-bit, 20 MSPS pipelined analog-to-digital converter (ADC) housed in a 28-pin SSOP package. It supports a single 5V analog supply, provides an internal reference (with optional external reference), and features a flexible input range programmable between 2 Vp-p and 5 Vp-p. The 20 MSPS sampling rate, 12-bit resolution, and pipelined architecture make it suitable for mid-speed data acquisition, CCD imaging, video digitisation, and digital communications baseband I/Q sampling. An ADC (Analog-to-Digital Converter) is a data-acquisition integrated circuit that samples continuous analog signals and converts each sample into a discrete digital code. Within the power-management and signal-chain taxonomy, the ADS805 belongs to the SAR/pipelined ADC family, the data-converter category, and the broader mixed-signal semiconductor hierarchy. Pipelined ADCs trade slightly higher latency (typically 3-5 clock cycles) for much higher sampling rates than successive-approximation (SAR) architectures, making them ideal for continuous-stream applications above 5 MSPS. Key features include 12-bit resolution with no missing codes, 20 MSPS maximum sampling rate, internal or external reference operation, an out-of-range indicator flag, single +5V supply operation, and a flexible parallel digital interface. The differential input stage is designed for ease of drive with a single op-amp in most configurations. The 2 Vp-p input range is the easiest to drive with a single op amp and provides the best spurious performance, while the 5 Vp-p range maximises dynamic range in low-noise front ends. The ADS805E uses a multi-stage pipelined architecture with proprietary error correction to achieve low differential non-linearity (DNL) and integral non-linearity (INL). The pin-compatible ADS804 (10 MSPS) and ADS803 (5 MSPS) allow designers to scale performance without PCB layout changes. The internal reference is laser-trimmed, and the part supports both CMOS-compatible and low-voltage differential outputs depending on configuration. Typical applications include digital video broadcast equipment, CCD-based imaging systems, document scanners, baseband I/Q sampling in software-defined radio, portable instrumentation, and industrial process control front ends. The combination of 5V single-supply operation and small 28-SSOP footprint suits space-constrained designs that require higher dynamic range than 8/10-bit alternatives. When designing with this device, ensure the analog input is properly buffered with a wideband op-amp capable of settling within half a clock cycle. The internal reference requires a stable bypass capacitor on the REFT/REFB pins; inadequate decoupling can degrade SNR by 1-2 dB. Power-supply rejection must be considered if the 5V rail is shared with switching converters.

Key verified characteristics include a maximum sampling rate of 53 MSPS, 12-bit resolution, 2 Vp-p to 3 Vp-p flexible input range, internal or external reference support, low differential nonlinearity of 0.5 LSB, and low power consumption of 335 mW. The converter also provides an out-of-range indicator, according to the verified component description. The architecture is designed for high-speed signal acquisition. The differential track-and-hold provides useful rejection of common-mode noise and helps suppress even-order harmonics. The pipelined ADC structure is appropriate when analog bandwidth, sampling rate, digital output timing, and signal integrity must be considered together rather than as independent specifications. Typical applications include communications receivers, digital oscilloscopes, frequency-domain analysis, radar and signal-processing front ends, video digitization, and industrial measurement systems. Differential input operation is useful when the source must be driven with balanced impedance and when common-mode rejection is important. PCB layout is critical because high-speed analog, clock, reference, and digital output paths must be controlled. Place input, reference, and decoupling networks close to the device, provide a clean return path, and follow the manufacturer pinout and layout guidance. Confirm package pin numbering and signal mapping against the official datasheet before layout release.

Within the broader hierarchy, the ADS808 sits under data converter -> ADC -> pipelined ADC -> high-speed ADC -> mixed-signal IC -> semiconductor. Pipelined ADCs are the dominant topology for communications, instrumentation, and imaging applications in the 10 MSPS to 250 MSPS range. Key features of the ADS808 include 70 MSPS sampling rate, selectable full-scale input range, internal or external voltage reference, a low-jitter 0.25 ps RMS track-and-hold, single 5V analog supply operation, and a powerdown mode for portable applications. The differential or single-ended clock input accepts TTL/CMOS/LVPECL swings and provides flexible timing for synchronization with downstream DSP or FPGA logic. Its premium track-and-hold maintains low distortion even at IF frequencies, simplifying front-end design in communications receivers. Typical applications for the ADS808Y/250 include CCD imaging digitizers, digital still cameras, basestation receiver IF digitizers, medical ultrasound beamformers, video processing, and high-speed data acquisition cards. The 12-bit/70-MSPS combination is well suited to digitizing signals in the 1 MHz to 35 MHz IF band where 70 dB SNR and SFDR are required for downstream demodulation. For test and measurement, the device serves as a general-purpose ADC front-end for digitizing oscilloscope channels and spectrum analyzer intermediate frequencies. When designing with the ADS808, place a 0.1 uF ceramic decoupling capacitor within 5 mm of every supply pin, and use a 10 uF bulk tantalum or ceramic capacitor on AVDD and DRVDD to suppress switching noise. Provide a clean, low-jitter clock source (jitter < 1 ps RMS) to preserve SNR at high input frequencies, and route analog and digital grounds on separate planes joined at a single point beneath the IC. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.

It integrates a premium 0.25 ps-rms-jitter track-and-hold, accepts single-ended or differential inputs, and operates from a single 5 V analog supply with flexible internal/external reference options and a powerdown pin for energy-aware systems. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time analog voltages into discrete digital codes at a sampling rate set by an external clock. Pipelined ADCs like the ADS808 use multiple low-resolution flash stages cascaded behind a high-bandwidth SHA, trading modest latency for very high sampling rates at moderate resolution. They sit within the broader hierarchy: ADC -> data converter -> mixed-signal IC -> power-management-and-signal-chain semiconductor. Key features include 70 MSPS guaranteed sampling rate, 12-bit resolution with no missing codes, selectable 1.0 Vpp or 2.0 Vpp full-scale input range, internal or external reference, and a low-jitter differential or single-ended clock input that accepts sine or square signals down to 0.5 Vp-p. The 48-HTQFP powerPAD package provides a thermal resistance of approximately 25 C/W with sufficient copper area, enabling reliable operation up to the 70 MHz clock rate. The architecture is a 12-stage pipelined ADC with digital error correction. Its track-and-hold bandwidth exceeds 100 MHz, and aperture jitter is specified at 0.25 ps rms, which is critical for preserving SNR when digitising IF signals above 30 MHz. Output data is delivered via a parallel CMOS interface compatible with standard DSPs and FPGAs. Typical applications include medical ultrasound imaging, digital video broadcast demodulation, CCD imaging digitisation, IF sampling in communications receivers, and industrial test instrumentation. The wide input bandwidth makes it particularly attractive for undersampling IF stages. When designing with this device, allocate adequate ground and supply decoupling (100 nF ceramic close to each supply pin plus a 10 uF bulk), and provide at least 1 square inch of PCB copper beneath the exposed pad. The /PD pin should be tied high for normal operation and pulled low for powerdown, reducing quiescent current for portable or energy-aware platforms. This page synthesizes distributor pricing, drop-in package-compatible alternatives, and practical PCB design guidance not always presented together in the manufacturer datasheet, giving engineers a single source for sourcing, selection, and layout decisions.

These figures come from the provided ADS820U search results and should be checked against the current manufacturer datasheet before design release. The monolithic converter uses a small-geometry CMOS process according to the TI product page. The internal track-and-hold captures the analog input before quantization, while the pipelined architecture supports throughput-oriented sampling. Configuration flexibility allows the same device family to accept either differential or single-ended input signals, which can simplify front-end design when common-mode rejection or single-ended source compatibility is required. The internal reference reduces the need for an external reference circuit in suitable applications. Typical uses include communications interfaces, industrial measurement, control loops, data-acquisition modules, embedded instrumentation, and embedded systems requiring parallel digital conversion. A 10-bit ADC is appropriate where the required system resolution does not justify the complexity and power of a higher-resolution converter. The 28-SOIC package is also useful for prototypes, legacy designs, and boards that already use through-hole or leaded analog interfaces. The main design consideration is ensuring that the analog input, reference, supply decoupling, digital output timing, and acquisition clock satisfy the converter requirements. Use the manufacturer datasheet for the exact pinout, input range, timing, output coding, reference accuracy, and recommended application circuit.

ADS821 - 10-Bit 40MSPS ADC Internal Ref | TI
The Texas Instruments ADS821 is a low-power, monolithic 10-bit, 40MHz analog-to-digital converter built on a small-geometry CMOS process. The complete converter integrates a 10-bit quantizer with an internal track-and-hold circuit, an internal reference, and a power-down feature, and is available in SO-28 and SSOP-28 packages. It operates from a single +5V supply and accepts either differential or single-ended input signals. A pipelined ADC is an analog-to-digital converter that uses a cascade of low-resolution stages to achieve high sampling rates while maintaining reasonable power consumption. In the ADC hierarchy, the ADS821 is a high-speed pipelined converter within the broader category of data converters, which sit between analog signals and digital signal processors in a signal chain. Pipelined ADCs are used where both high speed and moderate resolution (10 to 14 bits) are required. The ADS821 provides no missing codes, a high SNR of 58 dB, and power dissipation of only 380 mW at 40 MSPS, which is low for a 10-bit 40MHz CMOS converter. The integrated track-and-hold removes the need for an external sample-and-hold amplifier, and the internal reference reduces external component count. The power-down feature reduces system power during idle periods. Architecturally, the device uses a pipelined conversion architecture optimized for conversion rates up to 40 MSPS. Differential input capability improves common-mode rejection and reduces even-order harmonic distortion compared to single-ended drive. Digital outputs drive standard CMOS logic, simplifying interfacing to FPGAs, DSPs, or microcontrollers in single-supply +5V systems. Typical applications include medical ultrasound signal digitizing, video and CCD digitizing, digital oscilloscope front-ends, industrial data-acquisition boards, and communications IF sampling. The combination of internal reference, internal track-and-hold, and 40MSPS throughput makes the ADS821 an efficient building block for high-speed acquisition channels. When designing with the ADS821, use a low-impedance analog source or high-speed op-amp driver to ensure differential input settling within one sample period. Decouple all supply pins and keep the analog input path short and shielded for best SNR.
ADS821E - 10-Bit 40MSPS ADC w/ Internal Reference | TI/Burr-Brown
The Texas Instruments ADS821E (originally Burr-Brown) is a low-power, monolithic 10-bit, 40 MSPS analog-to-digital converter (ADC) with single-ended or differential inputs, an internal reference, an internal track-and-hold, and 9.3 effective bits of resolution, offered in a 28-pin SSOP package. According to the manufacturer datasheet, the converter consumes only 380 mW from a single +5 V analog supply, while delivering 58 dB SNR for high-fidelity digitization of intermediate-frequency signals, video, and baseband communications. The ADS821E provides CMOS-compatible digital outputs and is guaranteed to have no missing codes across the full operating temperature range. A successive-approximation-register (SAR) ADC, the ADS821E operates by sampling an input voltage once per conversion cycle and comparing it to an internal binary-weighted capacitor network through a precision comparator; unlike pipelined ADCs, the SAR architecture is fully specified on a single clock edge with no pipeline latency. SAR ADCs occupy a tier below flash ADCs in conversion speed but above delta-sigma ADCs in raw sample rate, and are widely deployed in industrial measurement, data acquisition, and instrumentation. The 28-pin SSOP package places all analog and digital pins on opposite sides of the die to minimize coupling and ease PCB layout separation. Key features include an internal 2.5 V reference (which can be overdriven externally), a track-and-hold amplifier front-end capable of handling input bandwidths well beyond Nyquist for undersampling applications, low differential nonlinearity for accurate code-edge transitions, and an output enable pin for bus multiplexing. The proprietary architecture provides excellent dynamic performance with spurious-free dynamic range suitable for IF-sampling communications receivers. Power-down mode reduces standby consumption to a few milliwatts for battery-portable designs. Typical applications include digital oscilloscopes and waveform digitizers, IF sampling for communications receivers, CCD imaging digitizers, portable medical imaging, baseband quadrature sampling in software-defined radios, and general-purpose high-speed data acquisition. The 40 MSPS sample rate and 10-bit resolution are well matched to display refresh rates and pixel-clock-driven video systems. When designing with this device, decouple the analog supply (AVDD) and digital supply (DVDD) domains separately with 0.1 µF ceramic capacitors placed within 5 mm of the supply pins. Maintain a single-point ground star connection under the AGND/DGND pins to avoid digital switching noise corrupting the analog input. Drive the analog input from a low-impedance, bandwidth-appropriate buffer for best spurious performance.

The Texas Instruments ADS821U is a 10-bit, 40-MSPS pipelined analog-to-digital converter with one single-ended or differential input, 58 dB SNR, 9.3-bit ENOB, an internal reference, and an internal track-and-hold circuit in a 28-pin SOIC (DW) package. Its 380 mW low-power design targets high-speed instrumentation where accurate sampling, compact size, and predictable signal acquisition are required. An ADC is a data-acquisition IC that samples an analog voltage and converts it into a digital code for processing by a microcontroller, DSP, FPGA, or test system. The ADS821U belongs to the pipeline ADC family, with its resolution, conversion rate, input architecture, reference, and acquisition circuitry defining its role within a broader analog-to-digital conversion and signal-processing hierarchy. The converter's principal features are 40 MSPS operation, 10-bit resolution, 58 dB SNR, and 9.3-bit ENOB. The no-missing-codes feature supports deterministic output behavior, while the internal track-and-hold circuit simplifies front-end design. The verified product information also identifies a 380 mW low-power figure and supports SOIC-28 and SSOP-28 family packaging, with ADS821U specifically supplied in the 28-pin SOIC package. Technically, the ADS821U is designed for single-ended or differential input acquisition. An internal reference and internal track-and-hold function reduce the number of external support blocks required in a conventional measurement chain. However, signal bandwidth, input range, timing, reference behavior, and electrical limits must be confirmed from the manufacturer datasheet before finalizing analog front-end and clock design. Typical uses include communications and signal-analysis equipment, industrial measurement systems, test and measurement instruments, and embedded control or processing platforms that need a 40-MSPS conversion rate. The 10-bit code width is appropriate where the required information bandwidth is greater than the precision demanded from every individual sample. A key design consideration is that the ADC does not replace the surrounding analog system. Input scaling, source impedance, anti-alias filtering, clock jitter, grounding, decoupling, and digital-interface timing determine practical performance. Confirm the pinout and pin functions in the official datasheet before layout or replacement work. This page combines verified manufacturer and distributor information with application guidance, practical design notes, and explicitly qualified replacement considerations. Unverified prices, complete pin functions, and unconfirmed cross-brand drop-in equivalents are not inferred.
ADS822E - 10-Bit, 40-MSPS Pipelined ADC | Texas Instruments
The Texas Instruments ADS822E is a 10-bit, single-channel, 40-MSPS pipelined analog-to-digital converter with single-ended or differential inputs and internal or external reference capability, packaged in a 28-pin SSOP. It is designed for high-speed signal acquisition where 10-bit conversion resolution and compact parallel-interface integration are more important than the very highest conversion rates. An ADC is a data-acquisition semiconductor that samples an analog voltage and converts it into a digital code. A pipelined ADC uses multiple internal stages that operate concurrently after the pipeline is filled. Compared with flash converters, this architecture can provide useful resolution at lower power and cost. The ADS822E belongs to the ADC hierarchy, integrates an analog input stage and digital quantizer, and supports acquisition, instrumentation, communications, and embedded measurement systems. The verified distributor data identifies a 10-bit converter with one input, one pipelined stage, and a 40-MSPS sampling rate. Its single-ended input supports the common source configuration used in many sensor and signal-chain systems, while differential operation can improve common-mode rejection when supported by the complete ADC implementation. The part uses a single +5 V supply according to the supplied comparison source, and the verified listing describes internal or external reference options. The ADS822E family is available in an SSOP-28 package. The manufacturer product page states that ADS822, ADS823, ADS825, ADS826, and ADS828 are pin-for-pin compatible, with the higher-speed members offering upgrade paths from the ADS822/ADS825 family. This compatibility is useful when a design needs more sampling rate without changing the board footprint or parallel interface layout. Typical applications include industrial sensor acquisition, communications infrastructure, portable measurement systems, medical instrumentation, and embedded data-acquisition platforms. Because the converter has a 40-MSPS maximum sampling rate, it is appropriate for waveforms within its Nyquist bandwidth rather than very high-frequency RF signals requiring a substantially faster converter. Designers should verify input range, timing, reference stability, output coding, and acquisition settling time against the manufacturer datasheet before finalizing a system. For PCB design, keep analog input, reference, supply, and digital return paths well controlled. The SSOP-28 device benefits from short analog traces, adequate bypassing, and separation between sensitive analog nodes and fast digital output lines. Use the manufacturer datasheet for the complete pinout, timing diagrams, electrical limits, and application-specific reference configuration.
ADS822EG4 - 10-Bit 40MSPS ADC w/ Int/Ext Ref | Texas Instruments
The Texas Instruments ADS822EG4 is a 10-bit, 40-MSPS analog-to-digital converter (ADC) that supports both single-ended and fully differential analog inputs in a 28-pin SSOP package. According to the TI ADS822 datasheet, the device delivers 60 dB SNR and 72 dBFS SFDR while consuming only 190 mW, and offers a programmable input range with internal or external reference selection. The G4 suffix designates the tube-packaged, RoHS-compliant ordering option. An ADC (analog-to-digital converter) is a data-acquisition integrated circuit that samples a continuous analog waveform and quantizes each sample into a digital code word. ADCs sit inside the broader hierarchy of data converters -> signal chain -> mixed-signal IC -> semiconductor. The 10-bit resolution and 40 MSPS sample rate place the ADS822 in the mid-speed, moderate-resolution tier used in industrial imaging, instrumentation, and communications baseband processing where 60-70 dB of dynamic range is acceptable. Key performance features include 60 dB SNR for clean signal capture, 72 dBFS spurious-free dynamic range (SFDR) to keep large-signal harmonics below the noise floor, and low differential nonlinearity (DNL) of 0.x LSB for code-density accuracy. The internal 2.5 V reference can be overridden by an external reference for designs requiring absolute accuracy or multi-ADC gain matching. The single-ended / differential input mode is pin-programmable, eliminating external signal-conditioning op-amps in many designs. The ADS822 uses a pipelined architecture with digital error correction, providing low latency and consistent sample-to-sample linearity. A separate analog and digital supply pin pair (AVDD/DVDD) is provided to isolate switching noise from the sensitive analog front-end. An internal reference buffer and duty-cycle equalizer simplify PCB layout and clock distribution. Typical applications include CCD/camera imaging digitizers, baseband I/Q sampling in software-defined radio, ultrasonic medical imaging front-ends, and portable test-and-measurement equipment. The 5 V analog supply and 28-SSOP footprint make it compatible with legacy industrial designs migrating from 8-bit ADCs. When designing with this device, place a 0.1 uF ceramic decoupling capacitor as close as possible to each AVDD/DVDD pin, and provide a solid ground plane under the package. The internal reference mode requires a 0.1 uF bypass on REF; for multi-ADC synchronization, drive the external reference pin from a single low-impedance source. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical design notes not found in the manufacturer datasheet, including cross-references to the pin-for-pin compatible ADS823 (60 MSPS), ADS825 (40 MSPS, single-ended optimized), ADS826 (60 MSPS), and ADS828 (75 MSPS) parts.

Its 10-bit resolution gives 1024 digital codes, while the 60-MSPS sampling rate supports high-speed acquisition. The 28-SSOP package is a surface-mount gull-wing package, but the verified snippets do not provide its exact dimensions. Typical uses include communications receivers, medical imaging instrumentation, industrial data acquisition, signal monitoring, and embedded control systems where a compact high-speed ADC is required. The parallel output requires a 10-bit data bus plus associated clock and control signals, so the surrounding digital system must be designed for the converter's timing and voltage requirements. Designers should use the manufacturer datasheet for the complete pinout, timing, electrical limits, reference recommendations, and layout requirements. Because the supplied evidence does not include complete pricing, stock, lead-time, or all pin-level details, those items remain explicitly marked or unavailable rather than inferred.

Differential input can be preferred for noisy analog environments, while single-ended operation can simplify front-end design when the source is referenced to ground. The 28-SSOP package provides a conventional surface-mount footprint, but the exact pinout and mechanical drawing should be confirmed against the manufacturer datasheet before layout. Designers should treat the ADC input as a high-bandwidth analog signal path. Keep input routing short, provide a suitable reference and bypass network, and observe the supply, clock, grounding, and digital-output requirements in the datasheet. Do not assume that a converter with the same family name is a drop-in replacement unless the package, pin mapping, reference configuration, input range, timing, and electrical limits all match.

For a new design, verify the required input range, reference source, digital interface timing, power sequencing, and thermal performance in the official ADS826E datasheet. Pricing and availability should also be checked with authorized distributors because the verified search data does not provide a current numeric price or lead time. A key design consideration is the analog input network. Input impedance, source capacitance, full-scale range, and the selected differential or single-ended topology must be evaluated together. Keep routing compact, provide the required bypass capacitors, and control clock and digital-output crosstalk. Because the verified data identifies the converter as a 60-MSPS, 10-bit pipelined ADC, PCB signal-integrity and clock routing decisions can materially affect sampling accuracy. This page consolidates the verified specifications, package information, source links, application guidance, and comparison framework for the ADS826E.

The QFN-64 package provides a compact footprint with an exposed thermal pad for heat dissipation. Typical applications include industrial process control, multi-channel data acquisition systems, medical instrumentation, optical networking power monitoring, and high-precision multi-axis servo control. The 4-channel input multiplexer allows time-multiplexed acquisition of up to four differential signals per IC, reducing board space and BOM cost in multi-sensor systems. Designers should pay close attention to PCB layout guidelines: route analog and digital grounds separately and join at a single point, place decoupling capacitors as close to the supply pins as possible, and use the exposed thermal pad for heat spreading. The on-chip reference requires an external bypass capacitor; refer to the datasheet for the recommended value. This page synthesizes distributor pricing, drop-in replacement alternatives, and practical design notes not found in the manufacturer datasheet. Engineers searching for multi-channel 18-bit SAR ADC solutions will find the integrated PGA and multiplexer of the ADS8284IRGCR to be a compelling, board-space-saving alternative to discrete ADC + driver + MUX implementations.
ADS828E - 10-Bit 75-MSPS Pipeline ADC | Texas Instruments
The Texas Instruments ADS828E is a 10-bit, 75-MSPS single-input pipeline analog-to-digital converter operating from a single +5 V supply in a 28-pin SSOP package. According to the TI product page, the converter supports single-ended input and can also be operated differentially for improved spurious performance. Its pipeline architecture supports 75 million samples per second, while the 10-bit quantizer targets applications requiring compact, high-speed digitization with parallel data output. An ADC is an analog-to-digital converter, a semiconductor that samples an analog voltage and converts it into a digital code for processing, storage, measurement, or transmission. The ADS828 belongs to the pipeline ADC and data-converter hierarchy, where internal stages operate in sequence to balance conversion speed with circuit complexity. The ADS828E is therefore positioned between general-purpose low-speed ADCs and more complex high-resolution high-speed converters. Key verified features include a resolution of 10 bits, a maximum sampling rate of 75 MSPS, one input, a pipelined architecture, and a 28-pin SSOP package. TI states that the ADS828 is pin compatible with the 10-bit, 40 MSPS ADS822 and ADS825, and with the 10-bit, 60 MSPS ADS823 and ADS826. That compatibility makes the ADS828E a potential board-level upgrade path when a design needs more sampling speed without changing its ADC footprint. The ADS828E is a pipeline CMOS ADC designed around single-ended input operation and differential operation for added spurious performance. Differential operation can help reduce common-mode sensitivity and may improve signal integrity when the analog front end and routing are designed appropriately. The exact input range, reference requirements, output timing, power consumption, and electrical limits were not supplied in the verified search excerpts, so those values must be confirmed in the manufacturer datasheet before design release. Typical uses include industrial control and data acquisition, communications infrastructure, instrumentation, signal monitoring, and embedded measurement systems. A 75-MSPS conversion rate is useful when the system must sample waveforms or rapidly changing analog signals, while 10-bit resolution suits control loops, diagnostics, and digital signal processing stages that do not require very high spectral resolution. The single +5 V supply also simplifies system power architecture compared with converters requiring multiple rails. The primary design consideration is to preserve analog signal integrity from the sensor or amplifier through the ADC input. Use short, controlled-impedance routing, a stable reference arrangement, and decoupling appropriate to the manufacturer recommendations. Confirm acquisition timing, output interface, input range, and clock polarity against the ADS828 datasheet. The page also identifies compatible ADS822E, ADS825E, ADS823E, and ADS826E family options, but their differing sampling rates should be treated as functional trade-offs rather than identical replacements. This product record consolidates the verified TI specifications, distributor identification, package information, and documented pin-compatible family references into an engineering-oriented selection and design reference.
