Product details
Overview
HMCAD1511 from Analog Devices is a high-speed, multi-mode 8-bit analog-to-digital converter (ADC) with time-interleaved architecture supporting single/dual/quad channel operation up to 1 GSPS, integrated crosspoint switch, 1–50× digital gain, and serial LVDS/RSDS output - used in USB-powered oscilloscopes and satellite receivers requiring wideband digitization at low power.
For engineers reviewing the HMCAD1511 datasheet, HMCAD1511 pinout, HMCAD1511 application, or HMCAD1511 equivalent, key selection considerations include its 7×7 mm QFN-48 package, 1.8 V supply, 49.8 dB SNR at 1 GSPS, 0.5 µs deep-sleep wake-up, and configurable channel mapping via SPI interface.
Technical Context
The HMCAD1511 employs time-interleaving across four internal ADC cores, with programmable clock division enabling single-clock operation across all modes (1 GSPS single, 500 MSPS dual, 250 MSPS quad). Its integrated crosspoint switch routes any of four differential analog inputs to any active ADC channel.
It features internal reference circuitry, digital offset correction, per-channel fine gain calibration, and serial SPI control for register-based configuration of power modes, data format (offset binary/2's complement), and channel enable/disable - designed for direct FPGA interfacing with LVDS/RSDS outputs and frame/data clocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed multi-channel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMCAD1520 | Pin-compatible; identical package and pinout; higher max sampling rate (1.25 GSPS single-channel) | Targets applications requiring >1 GSPS sampling, e.g., wider instantaneous bandwidth radar IF digitization | Select HMCAD1520 when >1 GSPS is required and layout reuse is critical; otherwise HMCAD1511 offers optimal power/performance trade-off. |
| HMCAD1510 | Pin-compatible and functionally configurable as HMCAD1510 via SPI; lower power (580 mW at 1 GSPS) but reduced SNR (48.5 dBFS) | Suitable for cost-sensitive or thermally constrained designs where 1.3 dB SNR margin is acceptable | Choose HMCAD1510 only if system-level SNR budget permits 1.3 dB degradation and lower power is prioritized over fidelity. |
Compared with HMCAD1520 and HMCAD1510, the HMCAD1511 delivers the best balance of 1 GSPS performance, 49.8 dB SNR, and 710 mW power in a field-proven 7×7 mm QFN package - making it the preferred choice for USB oscilloscopes and satellite IF receivers where fidelity and integration outweigh marginal speed or power differences.

FAQ
What is the maximum sampling rate supported by the HMCAD1511 in single-channel mode?
The HMCAD1511 supports a maximum sampling rate of 1000 MSPS in single-channel mode. This is confirmed in the Electrical Specifications section under "Clock Inputs" where FSmax for single-channel mode is specified as 1000 MSPS. The device maintains 49.8 dB SNR and 650 MHz full-power bandwidth at this rate, making it suitable for high-fidelity digitization of wideband analog signals. The HMCAD1511 achieves this using time-interleaved architecture across its four internal ADC cores.
Does the HMCAD1511 require external reference components?
No, the HMCAD1511 does not require external reference components. Its General Description explicitly states it includes "internal reference circuitry with no external components required." This integrated reference supports consistent 2 Vpp full-scale differential input range and enables simplified PCB layout and reduced BOM count. The HMCAD1511 also features internal digital offset correction, further reducing system calibration complexity while maintaining ±0.5 LSB INL and ±0.2 LSB DNL performance.
How many differential analog inputs does the HMCAD1511 have, and how are they routed?
The HMCAD1511 has four differential analog input pairs: IP1/IN1 through IP4/IN4. These are routed via an integrated crosspoint switch that activates the user-selected input for each active ADC channel. In single-channel mode, one of the four inputs is selected as the valid source; in dual-channel mode, any two inputs can be assigned independently; and in quad-channel mode, each input maps to one ADC channel. This routing is controlled entirely through the SPI interface and requires no external switching hardware.
What digital output standards does the HMCAD1511 support?
The HMCAD1511 supports both LVDS and RSDS digital output standards. Its data outputs (DP1A/DN1A through DP4B/DN4B), bit clock (LCLKP/LCLKN), and frame clock (FCLKP/FCLKN) are LVDS-compatible by default, with RSDS levels also supported per AC Specifications. Output common-mode voltage is fixed at 1.2 V, and differential swing is 350 mV for LVDS and 150 mV for RSDS. This dual-standard compliance ensures interoperability with a broad range of FPGAs and ASIC receivers.
Is the HMCAD1511 pin-compatible with other devices in its family?
Yes, the HMCAD1511 is pin-compatible with both HMCAD1520 and HMCAD1510. The documentation explicitly states "HMCAD1511 is pin compatible with HMCAD1520" and "HMCAD1511 is pin compatible and can be configured to operate as HMCAD1510." This enables drop-in replacement in existing layouts, though functional behavior (e.g., max sampling rate, power, SNR) differs between variants. Pin compatibility covers the 7×7 mm QFN-48 LP7D package and identical pin numbering/function mapping per Table 3.
