Product details
Overview
ADS5500IPAPR from Texas Instruments is a 14-bit, 125 Msps pipeline analog-to-digital converter with 71.2 dBFS SNR at 100-MHz fIN, 82 dBc SFDR, 2.3-VPP differential input range, and internal voltage reference. It operates from a single 3.3-V supply, dissipates 578 mW analog power, and targets high-dynamic-range digitization in space-constrained communication receivers and test instrumentation.
For engineers reviewing the ADS5500IPAPR datasheet, ADS5500IPAPR pinout, ADS5500IPAPR application, or ADS5500IPAPR equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-grade temperature operation (–40°C to 85°C), HTQFP-64 PowerPAD™ package details, and two rigorously cross-checked alternative ADCs for 14-bit/125-Msps signal acquisition systems.
Technical Context
The ADS5500IPAPR implements a switched-capacitor pipeline architecture with dual-edge clocking-both rising and falling edges advance samples through stages-achieving 17.5-clock-cycle latency. Its integrated sample-and-hold stage supports 750-MHz analog input bandwidth and accepts 2.3-VPP differential inputs referenced to 1.55 V common-mode voltage.
A configurable DLL enables stable operation across 60–125 Msps (DLL ON) or 2–80 Msps (DLL OFF); serial programming via SEN/SDATA/SCLK configures DFS, test modes, and power-down. CMOS-compatible parallel outputs (D0–D13, OVR, CLKOUT) interface directly to FPGA or ASIC logic without level-shifting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS5560IRGZT | 16-bit, 40 Msps; higher resolution but lower speed; 1.8-V digital I/O; no internal reference | Better for precision DC-coupled measurements; unsuitable for 125 Msps IF sampling | Select when ENOB > 13.5 bits is mandatory and sample rate ≤ 40 Msps suffices |
| AD9446BSTZ-105 | 16-bit, 105 Msps; 3.3-V supply; external reference required; 105 Msps max (vs. 125 Msps) | Requires external REF and clock conditioning; higher power (1.2 W); larger 80-lead LQFP | Choose when legacy ADI ecosystem compatibility or marginally higher resolution outweighs size/power penalties |
Compared with ADS5500IPAPR, ADS5560IRGZT trades 45 Msps speed for +2-bit resolution and lower digital supply voltage, while AD9446BSTZ-105 offers 16-bit fidelity at 105 Msps but demands external support circuitry and consumes >2× the power-making ADS5500IPAPR optimal for compact, self-contained 14-bit/125-Msps systems.

FAQ
What is the guaranteed operating temperature range for ADS5500IPAPR?
The ADS5500IPAPR is specified for industrial-grade operation from –40°C to +85°C ambient temperature. All electrical parameters-including SNR, SFDR, and DNL-are characterized and guaranteed across this full range at 3.3-V supply and 125 Msps sampling rate. The device uses thermal metrics (θJA = 21.47°C/W) validated on JEDEC-standard 4-layer PCBs.
Does ADS5500IPAPR require an external reference voltage?
No, ADS5500IPAPR integrates a precision internal voltage reference with VREFP = 2.11 V and VREFM = 0.97 V, yielding a 1.14-V reference span. External 1-µF capacitors are required on REFP and REFM pins to ground for stability. No external reference IC or resistor network is needed for standard operation.
How is the output data format selected on ADS5500IPAPR?
The ADS5500IPAPR output format (straight binary or two's complement) and CLKOUT polarity are controlled by the DFS pin voltage level per Table 3 in the datasheet. Applying 0.8 V ≤ VDFS ≤ 1.4 V selects straight binary with rising-edge CLKOUT; 1.6 V ≤ VDFS ≤ DRVDD selects two's complement with falling-edge CLKOUT. No serial register write is required.
What is the latency of ADS5500IPAPR and how is it affected by clock configuration?
ADS5500IPAPR exhibits fixed 17.5-clock-cycle latency from input clock falling edge to valid D0–D13 output. This value is invariant across DLL ON/OFF modes and sampling rates (60–125 Msps). Latency remains deterministic because the pipeline advances on both clock edges-no variation occurs due to duty cycle or frequency changes within spec.
Can ADS5500IPAPR interface directly with 3.3-V FPGA I/O banks?
Yes, ADS5500IPAPR's parallel CMOS outputs (D0–D13, OVR, CLKOUT) are fully compatible with 3.3-V LVTTL/LVCMOS FPGA I/O standards. Output voltages meet VOH ≥ 2.8 V and VOL ≤ 0.3 V into 10-pF loads, and input thresholds align with FPGA VIH/VIL specs. No level shifters or series resistors are required for direct connection.
