ADS5102IPFBRG4 概要
A pipelined ADC is a high-speed converter architecture that processes the analog input through a cascade of low-resolution flash stages, each handling a successive bit of the conversion while the remainder of the pipeline samples the next input. Pipelined ADCs deliver sample rates from a few MSPS to over 100 MSPS with moderate resolution (8-14 bits) and excellent dynamic performance. They sit within the broader data-converter hierarchy as: ADC -> high-speed ADC -> pipelined ADC -> data converter IC -> signal chain semiconductor.
Key features of the ADS5102IPFBRG4 include 65 MSPS maximum sample rate, 1.8 V single-supply operation, internal or external reference selection, a flexible CMOS digital output interface, and a power-down pin that reduces quiescent current during idle periods. Per TI datasheet SLAS213, the ADS5102 family (ADS5102 at 65 MSPS; ADS5103 at 40 MSPS) shares the same 48-TQFP footprint, simplifying migration between speed grades. Differential input architecture provides common-mode noise rejection suited to single-ended-to-differential front-end drivers.
Typical applications include portable imaging systems, digital oscilloscope front-ends, IF-sampling communications receivers, video digitizers, and ultrasound beam-forming channels where 10-bit resolution at high sample rates is acceptable. The 48-TQFP (7x7) package supports standard reflow profiles and 1 mm-pitch PCB layouts. When designing with this device, pay attention to the input common-mode voltage and reference decoupling - the internal reference requires a 10 uF bypass capacitor on REFT/REFB pins to meet the specified linearity. The power-down pin must be driven logic-low for normal operation.

主な用途
ADS5102IPFBRG4 の用途: 6 件s: Portable Imaging Systems, Digital Oscilloscope Front-End, IF-Sampling Communications Receiver, Video Digitizer / Broadcast Equipment, Ultrasound Beam-Forming Channel, Industrial Process Control Data Acquisition.
Portable Imaging Systems
The ADS5102IPFBRG4's 65 MSPS sample rate at 10-bit resolution is well-matched to portable imaging front-ends such as handheld ultrasound and digital camera preview streams. Operating from a single 1.8 V rail with 3.3 V CMOS-compatible outputs, it interfaces directly to low-power FPGAs and DSPs without level shifters, reducing BOM and PCB area. The integrated power-down pin reduces quiescent current to less than 1 mW during idle frames, extending battery life in field-deployed medical and industrial imaging tools. Per TI datasheet SLAS213, the differential input architecture rejects common-mode noise from the analog front-end, improving SNR in electrically noisy clinical environments.
おすすめ
Digital Oscilloscope Front-End
In entry-level digital oscilloscope and digitizer designs, the ADS5102IPFBRG4 provides 65 MSPS sampling with 10-bit vertical resolution - sufficient for sub-30 MHz bandwidth measurement tools used in education, R&D benches, and field service. The pipelined architecture delivers consistent AC performance across the analog input bandwidth, and the 48-TQFP package fits standard 4-layer PCB layouts. According to TI datasheet SLAS213, designers pair the ADS5102 with an external track-and-hold amplifier and a low-jitter clock source for the best spurious performance in repetitive signal acquisition.
おすすめ
IF-Sampling Communications Receiver
The ADS5102IPFBRG4's 65 MSPS rate and wide analog input bandwidth make it suitable for narrowband IF-sampling in software-defined radio and fixed-wireless receivers. Sampling a 21.4 MHz or 43 MHz IF directly into the digital domain eliminates a downconversion stage and simplifies the receiver chain. Per TI datasheet SLAS213, designers should pair the ADC with a bandpass anti-aliasing filter and a low-phase-noise clock; the 1.8 V supply simplifies integration with modern baseband ASICs. The 3.3 V CMOS digital outputs interface directly to DSP data buses.
おすすめ
Video Digitizer / Broadcast Equipment
The ADS5102IPFBRG4 supports composite and component video digitizer boards requiring 65 MSPS sampling for SDTV formats (ITU-R BT.601). The 10-bit resolution preserves luma/chroma fidelity while the 1.8 V supply simplifies integration with modern video processing ASICs. Per TI datasheet SLAS213, the differential input architecture provides common-mode rejection of ground noise in rack-mounted broadcast chassis. The parallel CMOS outputs feed directly into FPGA video pipelines at clock rates up to 65 MHz without external buffering.
おすすめ
Ultrasound Beam-Forming Channel
Medical ultrasound beam-formers use 10-12 bit ADCs at 40-65 MSPS per channel; the ADS5102IPFBRG4 fits the 65 MSPS tier with 1.8 V single-supply operation and integrated power-down for thermal management. Its differential input accepts the output of standard ultrasound LNA/AGC front-ends. Per TI datasheet SLAS213, the part's low aperture jitter preserves phase coherence across multi-element transducer arrays - critical for beam-forming accuracy. The 48-TQFP package supports dense multi-board stacked-array designs where each PCB carries many ADC channels.
おすすめ
Industrial Process Control Data Acquisition
In industrial data acquisition modules that sample transducer outputs at moderate rates, the ADS5102IPFBRG4's 65 MSPS throughput is typically de-rated to 10 MSPS or lower in oversampling configurations to gain effective resolution. The industrial -40 C to +85 C operating range supports factory floor deployment. Per TI datasheet SLAS213, the internal reference option eliminates external precision reference ICs, reducing BOM cost; the differential input rejects common-mode noise from long sensor cable runs in plant environments.

設計ノート
The ADS5102IPFBRG4 operates from a single 1.8 V supply for both AVDD and DVDD, but the digital outputs swing to 3.3 V CMOS levels for direct interface to standard logic. Place a 0.1 uF ceramic decoupling capacitor within 5 mm of each AVDD pin and a 10 uF bulk capacitor on the supply rail. The internal reference requires a 10 uF capacitor on REFT and REFB pins; per TI datasheet SLAS213, omitting these caps degrades INL/DNL significantly.
Use a 4-layer PCB with a dedicated ground plane beneath the 48-TQFP package to control digital-output coupling into the analog input traces. Route the differential analog inputs as a matched-length, 100 ohm differential pair on the top layer with continuous ground reference underneath. Keep the input clock trace short and isolated from analog signals to minimize aperture-jitter-induced SNR degradation.
Estimated: power consumption at 65 MSPS is approximately 60 mW based on the 1.8 V supply and typical analog/digital current. Do not operate the digital outputs above 3.3 V CMOS levels - the part's output drivers are not 5 V tolerant. Drive the power-down input actively; leaving it floating can put the device into an indeterminate state and increase quiescent current.
