Product details
Overview
ADS5522IPAP from Texas Instruments is a 12-bit, 80 MSPS analog-to-digital converter (ADC) with integrated sample-and-hold and internal voltage reference. It delivers 69.7 dBFS SNR at 100 MHz input, 83 dBc SFDR, 2.3-VPP differential input range, and operates from a single 3.3-V supply with 541 mW analog power dissipation. It serves as the front-end digitizer in high-speed communication receivers and radar systems.
For engineers reviewing the ADS5522IPAP datasheet, ADS5522IPAP pinout, ADS5522IPAP application, or ADS5522IPAP equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative ADCs for 80 MSPS, 12-bit sampling systems requiring industrial temperature range operation and CMOS-compatible parallel output.
Technical Context
The ADS5522IPAP implements a 12-bit pipeline ADC core with on-chip linear S&H and internal reference (REFP = 2.15 V, REFM = 1 V). Its timing architecture supports 80 MSPS sampling with 17.5-clock-cycle latency and aperture jitter of 300 fs, enabling precise synchronization in undersampling RF receiver chains.
Differential clock inputs (CLKP/CLKM) drive sampling; parallel CMOS outputs (D0–D11) are driven by DRVDD and synchronized to CLKOUT. Serial programming via SCLK/SDATA/SEN configures test modes, power-down, and data format-supporting straight binary or two's complement with selectable CLKOUT polarity via DFS pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Sample Rate | 80 MSPS - supports Nyquist-bandwidth up to 40 MHz or IF undersampling up to 220 MHz |
| SNR @ 100 MHz fIN | 69.7 dBFS - limits dynamic range to ~11.6 effective bits in wideband RF capture |
| SFDR @ 100 MHz fIN | 83 dBc - determines spurious-free signal fidelity for multi-tone baseband or IF signals |

Key Features
| Feature | Design Value |
|---|---|
| Integrated voltage reference | REFP = 2.15 V, REFM = 1 V, ±4% error - eliminates external reference IC and reduces BOM count |
| Low aperture jitter | 300 fs - enables high IF sampling without significant SNR degradation above 100 MHz |
| Serial configuration interface | 3-wire (SEN/SCLK/SDATA) - allows runtime reconfiguration of test modes and power-down without hardware change |
| Power-down mode | Standby power = 180–250 mW - reduces system power during idle periods while retaining register state |
| OVR over-range indicator | Dedicated open-drain output (Pin 64) - flags input saturation in real time for AGC or clipping mitigation logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS5521IPAP | 12-bit, 105 MSPS; identical pinout and serial interface; higher power (620 mW); SNR = 69.2 dBFS @ 100 MHz | Supports wider Nyquist zone (52.5 MHz) but requires tighter clock jitter control | Select when sampling rate >80 MSPS is mandatory and board layout accommodates +79 mW dissipation |

FAQ
What is the maximum analog input frequency supported by the ADS5522IPAP?
The ADS5522IPAP specifies an analog input bandwidth of 750 MHz when driven from a 50-Ω source. This enables direct sampling of RF/IF signals up to ~220 MHz while maintaining ≥65 dBFS SNR, making it suitable for undersampling architectures in communications and radar. Performance degrades gradually beyond 220 MHz due to internal front-end roll-off.
Does the ADS5522IPAP require external reference components?
No, the ADS5522IPAP includes an internal voltage reference with REFP = 2.15 V and REFM = 1 V, and reference error of ±4%. External 1-μF capacitors (with 1-Ω series resistors) are required on REFP and REFM pins per datasheet Figure 37, but no precision external reference IC is needed-reducing system cost and board area.
How does the serial programming interface of the ADS5522IPAP operate?
The ADS5522IPAP uses a three-wire serial interface (SEN, SCLK, SDATA) that latches 16-bit register words on the falling edge of SCLK while SEN is low. The first 4 bits are the register address; the last 12 bits are data. Minimum valid word length is 16 clocks; excess bits are ignored. ADS5522IPAP supports runtime configuration of test modes, power-down, and data format without reset.
What is the purpose of the OVR pin on the ADS5522IPAP?
The OVR (Over-Range) pin (Pin 64) is an open-drain output that asserts high when the analog input exceeds the 2.3-VPP full-scale range. It provides real-time saturation detection for automatic gain control (AGC) loops or clipping mitigation logic in receiver chains-enabling immediate response without parsing full 12-bit data streams in FPGA firmware.
Can the ADS5522IPAP be used with a single-ended clock input?
No, the ADS5522IPAP requires a differential clock input (CLKP/CLKM) per its absolute maximum and recommended operating conditions. Driving only one clock pin violates the common-mode specification and degrades aperture jitter and SNR. A transformer or differential clock buffer (e.g., LMH1218) must be used to convert single-ended sources to compliant 1–3 VPP differential signals.
