Product details
Overview
ADS58B19IRGZR from Texas Instruments is a 9-bit, 250MSPS ultralow-power analog-to-digital converter with integrated high-impedance analog input buffer and DDR LVDS/CMOS digital output interface. It delivers 55.7dBFS SNR and 76dBc SFDR at 150MHz input frequency, operates from 1.8V analog and digital supplies, and targets wideband communications receiver chains requiring low power and high dynamic performance.
For engineers reviewing the ADS58B19IRGZR datasheet, ADS58B19IRGZR pinout, ADS58B19IRGZR application, or ADS58B19IRGZR equivalent, this page provides verified specifications, QFN-48 package layout, real-world use cases in PA linearization and broadband receivers, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The ADS58B19IRGZR implements a buffered pipeline ADC architecture with constant-input-impedance analog front-end, enabling stable performance up to 600MHz analog input frequency at 1VPP amplitude. Its SNRBoost technology is disabled (not applicable), distinguishing it from the ADS58B18 variant.
It supports dual-output modes: DDR LVDS (350mV or 200mV swing, 100Ω termination) and 1.8V parallel CMOS, with programmable gain for SNR/SFDR trade-off and on-chip DC offset correction. Dynamic power scaling reduces current draw at lower sampling rates without performance loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 9-bit - fixed quantization depth defining LSB step size and full-scale range mapping |
| Max Sampling Rate | 250MSPS - maximum clock rate enabling Nyquist bandwidth up to 125MHz |
| SNR @ 150MHz | 55.7dBFS - signal-to-noise ratio limiting detectable signal floor in wideband IF sampling |
| SFDR @ 150MHz | 76dBc - spurious-free dynamic range determining usable instantaneous bandwidth before distortion dominates |
| Analog Power | 258mW at 200MSPS - actual analog supply consumption (AVDD + AVDD_BUF), scalable downward at lower rates |
| Digital Interface | DDR LVDS or 1.8V CMOS - dual-mode output supporting FPGA-compatible low-jitter serialization or direct microcontroller connection |
| Input Bandwidth | 550MHz - analog input small-signal bandwidth enabling accurate digitization of multi-carrier RF signals |
Pinout & Package
ADS58B19IRGZR is housed in a 7mm × 7mm QFN-48 package (RGZ) with exposed thermal pad connected to DRGND. Pin assignments are identical for LVDS and CMOS modes except for D0–D10 signal routing and CLKOUT/CLKOUTP/M pin usage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INP / INM | Differential analog input | High-impedance buffered inputs accepting ±0.75VPP differential signal; common-mode voltage set by VCM pin |
| CLKP / CLKM | Differential clock input | Accepts LVDS/LVPECL/LVCMOS clocks; supports 30–250MSPS with 0.2–1.5VPP differential amplitude |
| D0_P / D0_M through D9_D10_P / D9_D10_M | DDR LVDS data outputs | Multiplexed 9-bit data (D0–D8) plus frame sync on D9/D10; 350mV or 200mV swing, 100Ω termination required |
| DRVDD / DRGND | Digital supply and ground | 1.8V digital core and output buffers; DRGND pad ties to thermal pad for thermal dissipation |
| RESET / SCLK / SDATA / SEN | Serial configuration interface | 4-wire SPI-like control bus; RESET must be pulsed high to initialize registers; SEN unused on ADS58B19 |
| VCM | Analog common-mode reference | 1.7V output used to bias external input network; enables dc-coupled signal chain design |
Key Features
| Feature | Design Value |
|---|---|
| Integrated analog input buffer | 4kΩ differential input resistance and 2.1pF capacitance maintained across 550MHz bandwidth, eliminating external driver requirements |
| Dynamic power scaling | Global power-down draws only 10–35mW; standby mode consumes 185mW; analog/digital currents scale linearly with sample rate |
| Programmable LVDS output strength | Configurable 100Ω or 50Ω termination drive capability supports both standard and low-swing LVDS signaling |
| DC offset correction loop | On-chip auto-calibration cancels ADC core offset error (±15mV max), improving baseband accuracy without external trimming |
| Low-clock-amplitude support | Accepts 0.2VPP differential clock input, enabling direct connection to low-power clock synthesizers or attenuated sources |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS58B18IRGZR | 11-bit, 200MSPS; includes SNRBoost for enhanced SNR in narrow bandwidths; higher analog power (258mW vs. same) | Preferred when >65dBFS SNR needed in <20MHz bandwidths (e.g., narrowband radar); not drop-in due to different resolution and timing | Select ADS58B18IRGZR if system requires higher resolution and SNRBoost-enabled sub-Nyquist processing; verify FPGA data path width compatibility. |
| ADS42JB49IRGCT | 14-bit, 250MSPS; JESD204B serial interface; no analog buffer; higher power (720mW total) | Used in high-precision instrumentation and phased-array radar where JESD204B simplifies board routing and SNR >70dBFS is mandatory | Choose ADS42JB49IRGCT only when JESD204B interface and 14-bit resolution justify added power and complexity; not pin-compatible. |
Compared with ADS58B19IRGZR, ADS58B18IRGZR trades speed for resolution and SNRBoost capability, while ADS42JB49IRGCT replaces parallel LVDS with JESD204B and adds 5 bits of resolution at significantly higher power and cost-making ADS58B19IRGZR optimal for power-constrained wideband communications where 9-bit fidelity suffices.

FAQ
What is the maximum analog input frequency supported by ADS58B19IRGZR?
The ADS58B19IRGZR supports up to 600MHz analog input frequency when driven with 1VPP differential amplitude, and 400MHz at 1.5VPP. This is enabled by its 550MHz analog input bandwidth and buffered front-end, making it suitable for undersampling RF signals in direct-conversion receivers and spectrum monitoring applications.
Does ADS58B19IRGZR support SNRBoost technology?
No, ADS58B19IRGZR does not support SNRBoost technology. That feature is exclusive to the ADS58B18 variant. The ADS58B19IRGZR is a 9-bit device optimized for higher sampling rate (250MSPS) and lower power, with no SNRBoost_En pin functionality-pin 23 is unused per the datasheet.
What are the power supply requirements for ADS58B19IRGZR?
ADS58B19IRGZR requires three independent supplies: AVDD = 1.7–1.9V (analog core), AVDD_BUF = 3.0–3.6V (input buffer), and DRVDD = 1.7–1.9V (digital outputs). Typical total power at 250MSPS is 327mW (258mW analog + 69mW I/O), with dynamic scaling reducing consumption at lower sample rates.
Can ADS58B19IRGZR operate in CMOS output mode?
Yes, ADS58B19IRGZR supports 1.8V parallel CMOS output mode via the DFS pin. In CMOS mode, it outputs non-multiplexed D0–D9 signals with 8pF load capability, consuming ~47–63mW depending on frequency and load. LVDS remains the default; CMOS mode trades interface simplicity for higher power and reduced noise immunity.
What is the function of the VCM pin on ADS58B19IRGZR?
The VCM pin on ADS58B19IRGZR outputs a stable 1.7V common-mode reference used to bias the external analog input network. It provides 4mA drive capability and enables dc-coupled signal paths, ensuring consistent input common-mode voltage regardless of source impedance-critical for maintaining linearity in buffered front-ends.
