Product details
Overview
ADS5483IRGC25 from Texas Instruments is a 16-bit, 135-MSPS analog-to-digital converter (ADC) with 95 dBc SFDR at 70 MHz input and 78.6 dBFS SNR at 135 MSPS. It features on-chip high-impedance analog buffering, internal reference generation, and DDR LVDS-compatible outputs. Designed for wireless infrastructure baseband sampling and radar digitization where high dynamic range and low noise are critical.
For engineers reviewing the ADS5483IRGC25 datasheet, ADS5483IRGC25 pinout, ADS5483IRGC25 application, or ADS5483IRGC25 equivalent, this page delivers verified electrical specs, QFN-64 PowerPAD™ package mapping, latency-critical timing data (5-cycle latency), dither-enabled spurious suppression, and validated alternatives for multi-carrier GSM/WCDMA/LTE receiver design.
Technical Context
The ADS5483IRGC25 uses a complementary bipolar (BiCom3) process and integrates a track-and-hold with high-impedance analog input buffer to isolate source loading. Its dual-supply architecture (5 V AVDD5 + 3.3 V AVDD3/DVDD3) enables optimized analog front-end headroom and low-noise digital output drive.
It employs DDR LVDS output formatting with even/odd bit interleaving across eight differential pairs plus DRY clockout, supporting deterministic 5-clock-cycle latency and sub-1 ps aperture jitter (80 fs rms). Internal dithering improves SFDR by suppressing harmonic spurs in narrowband applications.

FAQ
What is the maximum input frequency supported by ADS5483IRGC25?
The ADS5483IRGC25 has an analog input bandwidth of 485 MHz (–3 dB), allowing it to directly sample IF signals up to approximately 240 MHz in the first Nyquist zone. For 135-MSPS operation, the practical input frequency range extends to 67.5 MHz for baseband sampling, but its wide analog bandwidth supports undersampling applications in L-band radar and communications.
Does ADS5483IRGC25 require external reference voltage?
No. ADS5483IRGC25 includes an internal 1.2-V reference generator (VREF) and self-biased analog input common-mode voltage (VCM = 3.1 V). External reference is optional: pulling both PDWNF and PDWNS high disables the internal reference, enabling use of an external 1.2-V source via the REF pin (Pin 4).
How does the dither function improve performance in ADS5483IRGC25?
Enabling the DITHER pin (logic high) injects controlled noise into the ADC's quantization path, randomizing harmonic distortion and reducing discrete spurious tones. This increases SFDR by up to 6 dB in narrowband FFT analysis-critical for detecting low-level signals near strong interferers in wireless receivers.
What is the power consumption of ADS5483IRGC25 in normal operation?
In normal operation at 135 MSPS, ADS5483IRGC25 draws 317 mA from AVDD5 (5 V), 133 mA from AVDD3 (3.3 V), and 60 mA from DVDD3 (3.3 V), totaling 2.2 W typical power dissipation. Deep-sleep mode reduces total power to 70 mW, ideal for burst-mode radar or battery-backed instrumentation.
Is ADS5483IRGC25 pin-compatible with other devices in the ADS548x family?
Yes. ADS5483IRGC25 shares identical QFN-64 PowerPAD™ packaging, pinout, and footprint with ADS5481IRGC25 and ADS5482IRGC25. All three devices are drop-in replacements with identical terminal functions-only clock rate, SFDR, and SNR differ per variant.
