ADS830E - 8-Bit 60MSPS Pipeline ADC | Texas Instruments
MPN: ADS830E ✓ AktifADS830E Ringkasan
Key specifications include 60 MHz maximum sampling rate, 49.5 dB SNR, and 170 mW typical power dissipation. The part supports an internal or external reference and offers both single-ended and differential analog inputs with a programmable input range of 1 Vp-p or 2 Vp-p, with the single-ended input span of 1.5V to 3.5V centered at 2.5V.
The ADS830E employs a pipelined CMOS architecture with an internal high-bandwidth track-and-hold and 8-bit quantizer. DNL is specified at 0.2 LSB, preserving linearity for accurate signal capture. The architecture supports an internal reference or an external reference, giving designers flexibility in frequency planning and absolute accuracy.
Typical applications include medical imaging front-ends, video digitizing systems, CCD/camera signal processing, IF sampling in communications, and portable instrumentation. The 60 MSPS sampling rate enables full baseband capture of standard-definition video and intermediate-frequency downconversion paths up to several tens of MHz.
When designing with the ADS830E, ensure the analog input network is configured to either single-ended (1 Vp-p or 2 Vp-p) or differential topology per the programmable range. Bypass the analog supply pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, and keep digital outputs routed away from analog inputs to minimize coupling.

Aplikasi Umum
ADS830E cocok untuk 6 aplikasis: Medical Imaging Front-End, Video Digitizing Systems, CCD/Camera Signal Processing, IF Sampling in Communications, Portable Test & Measurement, Industrial Imaging & Inspection.
Medical Imaging Front-End
The ADS830E's 60 MSPS sample rate and 8-bit resolution suit compact ultrasound and patient-monitoring front-ends where signal bandwidth fits within 30 MHz. The 49.5 dB SNR provides sufficient dynamic range for echo envelopes captured at 10-20 MHz IF, while the 170 mW dissipation keeps thermal rise inside portable cart enclosures. The SSOP-20 footprint integrates easily next to TI's AFE5805 or AFE5807 analog front-end, enabling multi-channel capture on a 4-layer PCB.

Video Digitizing Systems
For SDTV and standard-definition broadcast capture, the ADS830E samples 27 MHz pixel-rate video with full Nyquist margin and 0.2 LSB DNL preserves amplitude accuracy across frame transitions. Place the ADC on the same board as a video decoder (e.g., TVP5150) to digitize composite or component video without an external anti-alias filter complexity. The +5V single-supply operation eliminates the negative rail supply typically required for legacy video ADCs.

CCD/Camera Signal Processing
Industrial and machine-vision cameras use the ADS830E to digitize analog CCD output streams at 30-60 MSPS with 49.5 dB SNR. The 1 Vp-p / 2 Vp-p programmable input range matches typical CCD output levels without external scaling. Designers pair it with a TI LMH6624 or LMH6723 output buffer to drive the ADC input, while a CPLD clocks the conversion and reads the 8-bit parallel bus into a frame buffer.

IF Sampling in Communications
Software-defined radio and IF-sampling receivers use the ADS830E to digitize 10-30 MHz intermediate-frequency signals at 60 MSPS, eliminating the analog quadrature demodulator stage. The differential input mode rejects common-mode LO feedthrough and improves spurious performance by 6-8 dB relative to single-ended. Pair the ADC with a TI GC5016 or GC5316 digital downconverter to extract I/Q baseband channels directly from the sampled stream.

Portable Test & Measurement
Handheld oscilloscope, spectrum analyzer, and data-acquisition front-ends leverage the ADS830E for its 170 mW dissipation and 8-bit resolution that fits a 60 MHz -3 dB input bandwidth. Battery-powered instruments run directly from a +5V LDO rail such as the TPS7A4701, simplifying power architecture. A MicroStrain or LCMXO2-256HC-4SG32C FPGA buffers sample bursts and streams them to USB or SD card storage.

Industrial Imaging & Inspection
Machine-vision and AOI (automated optical inspection) systems use the ADS830E to digitize line-scan camera output at 60 MHz, supporting conveyor speeds up to several meters per second. The 1 Vp-p / 2 Vp-p input range matches typical line-scan sensor outputs, and the SSOP-20 footprint mounts adjacent to TI's SN65LVDS31 drivers for long-distance backplane transmission. Industrial temperature grade (-40 C to +85 C) supports factory-floor deployment.

Catatan Desain
Estimated: at +5V single supply and 170 mW dissipation, the SSOP-20 junction-to-ambient thermal resistance (theta_JA) of ~80 C/W produces a temperature rise of about 14 C above ambient - adequate margin to 125 C junction limit. Bypass the AVDD pin (pin 7) with a 0.1 uF X7R ceramic placed within 5 mm of the pin, plus a 10 uF tantalum bulk capacitor for transient suppression. Route analog and digital grounds to a single star-ground point near the AGND pins to avoid ground-loop noise coupling into the analog input.
Keep the analog input trace and clock trace short and matched in length. Use a 50-ohm controlled-impedance microstrip if traces exceed 25 mm. Place a 0.1 uF X7R ceramic between REFT/REFB (pins 4/5) and CM (pin 6) to filter reference noise. Route digital outputs D0-D7 away from the IN pin by at least 3 trace widths to minimize digital-to-analog crosstalk into the input network.
Do not exceed the absolute maximum analog input of AVDD+0.3V; the input ESD structure clamps at the rail. Drive the CLK pin with a low-jitter (< 50 ps RMS) CMOS driver such as an SN74LVC1G34 or a TI CDCLVC1310 clock buffer; jitter directly degrades SNR. When operating with an external reference, leave the REFTS/REFBS pins (2, 3) properly bypassed or floating per the datasheet reference-mode table to avoid drift in the internal reference ladder.
