ADC08D1500CIYB - Dual 1.5 GSPS 8-Bit ADC | Texas Instruments
MPN: ADC08D1500CIYBADC08D1500CIYB نظرة عامة
An 8-bit ADC is a converter that translates an analog input voltage into one of 256 discrete digital codes (2^8) at a specified sample rate, typically expressed in MSPS (mega-samples per second) or GSPS (giga-samples per second). The ADC08D1500 belongs to the high-speed ADC family, within the data converter IC category, under the broader integrated circuits taxonomy. Its folding and interpolating architecture reduces the number of comparators required compared with a flash ADC, lowering power consumption while maintaining high sampling rates suitable for wideband signal capture.
Key features of the ADC08D1500CIYB include its folding and interpolating architecture, dual-channel sampling up to 1.5 GSPS per channel, single 1.9 V supply operation, LVDS/parallel output interface, and an integrated input multiplexer. The 128-pin HLQFP package supports high pin counts required for parallel LVDS output buses and dedicated analog/digital supply domains. The device is ensured to have no missing codes across the full operating temperature range, which is critical for instrumentation applications where linearity must be guaranteed.
The ADC08D1500CIYB uses a unique folding and interpolating topology that combines the speed of flash conversion with significantly reduced comparator count and lower input capacitance. This architecture yields excellent dynamic performance with reduced power dissipation relative to full-flash converters of equivalent speed. The single 1.9 V supply simplifies power-tree design, and the LVDS-compatible outputs minimize EMI in densely populated PCB layouts operating at multi-GSPS data rates.
Typical applications include wideband test and measurement instrumentation, radar and lidar signal processing, high-speed data acquisition systems, software-defined radio (SDR), medical imaging front ends, and communications infrastructure including cable head-end equipment. The dual-channel capability enables direct sampling of I/Q baseband pairs or two independent IF channels, which is valuable in multi-channel receiver architectures where board area and BOM count are tightly constrained.
When designing with this device, the LVDS output bus requires matched 100 ohm differential termination and tightly controlled PCB trace lengths to maintain signal integrity at 1.5 GHz clock rates. Decoupling must include low-ESL ceramic capacitors placed within 2 mm of each supply pin, and a low-noise LDO is recommended for the AVDD rail to preserve ENOB.

التطبيقات النموذجية
ADC08D1500CIYB مناسب لـ 6 التطبيقs: Wideband Oscilloscope Front End, Software-Defined Radio (SDR) Receiver, Radar and Lidar Signal Processing, Medical Imaging Front End (Ultrasound), Communications Infrastructure (Cable Head-End), Automated Test Equipment (ATE) Digitizer.
Wideband Oscilloscope Front End
The ADC08D1500CIYB is well matched to wideband digital oscilloscope and digitizer front ends. Its dual 1.5 GSPS channels enable simultaneous sampling of two channels at full bandwidth, which is essential for 4-channel scope designs using two ADCs in a master-slave configuration. The 8-bit resolution suits the high-bandwidth acquisition paths (typically 1 GHz or above) where vertical resolution beyond 8 bits is not practical due to noise and aperture-jitter limits. The LVDS output bus streams digitized samples to an FPGA for triggering and display processing. Compared with newer TI ADC08D-series parts, the ADC08D1500's mature firmware ecosystem and TI reference schematics simplify ATE-grade oscilloscope designs.

Software-Defined Radio (SDR) Receiver
The ADC08D1500CIYB is widely deployed in software-defined radio platforms where direct RF sampling of IF signals is required. The dual 1.5 GSPS channels can capture direct-sampled IF signals up to roughly 750 MHz, sufficient for many narrowband and broadband SDR applications including spectrum monitoring, electronic warfare test beds, and wideband communications capture. The 8-bit ENOB at high input frequencies (~7.0-7.5 bits at Nyquist) supports 50+ dB SFDR, which is adequate for monitoring receivers and commercial wireless test. The single 1.9 V supply simplifies battery-powered and field-deployed SDR designs where power budget is critical.
موصى به
Radar and Lidar Signal Processing
The ADC08D1500CIYB suits automotive and surveillance radar baseband digitizers as well as lidar time-of-flight receivers. Its dual 1.5 GSPS channels can simultaneously digitize I and Q baseband pairs from a radar mixer, preserving phase information critical for moving target indication. The 8-bit resolution is sufficient for many pulsed-radar and FMCW-lidar applications where dynamic range is provided by range binning and matched filtering rather than per-sample resolution. The HLQFP-128 package's exposed thermal pad supports the ADC08D1500's 1.8 W dissipation at 1.5 GSPS with adequate PCB copper for thermal management in sealed enclosures.
موصى به
Medical Imaging Front End (Ultrasound)
The ADC08D1500CIYB can be used in ultrasound beamformer front ends and other medical imaging digitizer paths where multi-channel sampling at high rates is required. Its dual 1.5 GSPS channels support direct sampling of RF signals from ultrasound transducers after a TGC amplifier, capturing the full bandwidth of high-frequency probes. The 8-bit resolution, combined with oversampling and digital decimation, yields effective resolution suitable for B-mode display. TI's quality management system and the device's industrial temperature range support integration into medical equipment under IEC 60601 quality programs.
موصى به
Communications Infrastructure (Cable Head-End)
The ADC08D1500CIYB is used in cable TV head-end equipment and DOCSIS upstream receivers where multiple downstream or upstream channels must be digitized simultaneously. Its dual 1.5 GSPS channels can capture an entire cable spectrum segment (typically 1 GHz or 1.2 GHz) and apply digital channelization in an FPGA. The 1.9 V supply simplifies compliance with telecommunications power-supply standards. Compared with general-purpose ADCs, the ADC08D1500's guaranteed no-missing-codes specification supports the linearity demanded by dense QAM modulation schemes used in modern cable networks.
موصى به
Automated Test Equipment (ATE) Digitizer
The ADC08D1500CIYB fits ATE pin electronics and digital tester digitizer cards where high sample rate per channel is the primary requirement. The dual 1.5 GSPS channels enable two simultaneous test channels per ADC, lowering BOM cost for high-pin-count testers. The 8-bit resolution suits the parametric measurement unit (PMU) and waveform digitizer paths used in mixed-signal IC test. TI's long-term product program and authorized distributor stocking (per the verified distributor listings at 2026-10-12) support the multi-year lifecycle typical of ATE platforms.

ملاحظات التصميم
The ADC08D1500CIYB consumes approximately 1.8 W at 1.5 GSPS from a single 1.9 V supply. The analog AVDD and clock CLKVDD rails are sensitive to switching-noise coupling; use a low-noise LDO (such as TI TPS7A4701 or similar) per rail rather than a switching converter. Place 10 uF bulk plus 0.1 uF and 0.01 uF decoupling capacitors within 2 mm of each supply pin. Estimated: with 1.8 W total dissipation across the HLQFP-128 thermal pad and approximately theta_JA = 18 C/W on a 4-layer JEDEC test board with the exposed pad soldered, the junction temperature rise is approximately 32 C above ambient - well within the 125 C maximum at 85 C ambient.
The LVDS output bus operates at 750 MHz DDR (data clock DCLK) and must be routed with 100 ohm differential impedance. Maintain length matching within 5 mil across each LVDS pair, and keep pair-to-pair skew within 25 mil to preserve sample-to-sample alignment at the receiving FPGA. Use ground-plane shielding between LVDS pairs and adjacent noisy signals (clock traces, switching regulator nodes). The CLK+/CLK- input has the same requirement - length match within 5 mil and route as a 100 ohm differential pair directly from the clock generator.
Route analog inputs INA+/INA- and INB+/INB- as 100 ohm differential pairs from the input amplifier outputs. Keep analog input traces short (< 25 mm) and isolated from the digital LVDS outputs to minimize digital-noise coupling into the analog front end. The exposed thermal pad of the HLQFP-128 package MUST be soldered to a continuous ground plane on the top layer with multiple thermal vias (at least 16 vias in a 4x4 array) to a dedicated inner ground plane. Failure to solder the pad results in junction temperature rise of approximately 3x and likely thermal shutdown at full 1.5 GSPS operation.
Do not apply analog input signals before the AVDD and DVDD supplies have ramped and stabilized - the input ESD diodes can forward-bias and latch the part. Use a power sequencer or simply enable the input analog style after the supplies stabilize. Calibration is required after power-up; assert CAL by toggling the CAL pin or via the serial configuration interface, and wait for the calibration complete flag before starting clock acquisition. The TEST pin MUST be left floating (no connect) - tying it high or low places the device into factory test mode and disables normal operation.
