Product details
Overview
ADS8413IBRGZRG4 from Texas Instruments is a 16-bit, 2-MSPS SAR analog-to-digital converter with LVDS serial interface, internal 4.096-V reference, and unipolar differential input range (–4 V to +4 V). It delivers 92 dB SNR and –107 dB THD at 10 kHz, supports zero-latency operation at full speed, and targets high-speed data acquisition in medical instrumentation and closed-loop control systems.
For engineers reviewing the ADS8413IBRGZRG4 datasheet, ADS8413IBRGZRG4 pinout, ADS8413IBRGZRG4 application, or ADS8413IBRGZRG4 equivalent, key selection criteria include its 200-Mbps LVDS interface timing, ±2 LSB INL max, 48-pin QFN package thermal performance (θJA = 86°C/W), nap mode power reduction (125 mW), and daisy-chain/cascade configuration support for multi-channel synchronization.
Technical Context
The ADS8413IBRGZRG4 implements a capacitor-based successive approximation register (SAR) architecture with integrated sample-and-hold, enabling true zero-latency conversion at 2 MSPS. Its internal 4.096-V reference includes buffer and start-up time of 25 ms with 1-µF storage capacitor.
It features dual-mode LVDS serial interface: configurable 16-/8-bit data frame, selectable internal 200-MHz clock (CLK_I/E = 1) or external clock (CLK_I/E = 0), and dedicated SYNC_O/SDO/CLK_O signals supporting daisy-chain or cascade topologies up to four devices at full throughput.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit with no missing codes guaranteed - ensures monotonicity and full code coverage in precision measurement. |
| Sample Rate | 2 MSPS maximum throughput - enables real-time capture of signals up to 37.5 MHz small-signal bandwidth. |
| SNR / THD | 92 dB SNR and –107 dB THD at 10 kHz - meets dynamic range requirements for medical imaging and spectral analysis. |
| INL / DNL | ±2 LSB max INL and +1.5/–1 LSB max DNL - supports accurate DC-coupled measurements with <0.003% gain error. |
| Power Dissipation | 290 mW at 2 MSPS, 125 mW in nap mode, 5 µW in power-down - enables thermal management in dense PCB layouts. |
| Interface | 200-Mbps LVDS serial (SYNC_O/SDO/CLK_O) with 16-/8-bit frame mode - reduces trace count vs parallel ADCs and eases EMI control. |
| Input Range | Unipolar differential: –4 V to +4 V with VREF = 4.096 V - simplifies front-end design by eliminating external level-shifting for ±4-V sensors. |
Pinout & Package
ADS8413IBRGZRG4 is housed in a 48-pin QFN package (RGZ) with exposed thermal pad, footprint-compatible with JEDEC MO-220 variation VGGQ, and specified for –40°C to +85°C operation. Thermal impedance θJA is 86°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN / –IN (Pins 18, 19) | Analog differential input | Accepts –VREF to +VREF swing with common-mode at VREF/2; Ci = 25 pF, leakage ≤500 pA - minimizes loading on precision signal sources. |
| REFIN / REFOUT / REFM (Pins 13–14, 11–12) | Reference interface | Internal 4.096-V reference with 36 ppm/°C drift; REFM must connect to analog ground; REFOUT requires 1-µF storage cap - enables self-contained calibration without external reference IC. |
| CSTART+/– / CONVST (Pins 28–29, Pin 2) | Conversion trigger | Dual-input control: LVDS CSTART (differential) or CMOS CONVST (single-ended); rising edge initiates sampling - supports mixed-signal system integration with either logic family. |
| SDO+/– / CLK_O+/– / SYNC_O+/– (Pins 40–41, 38–39, 42–43) | LVDS serial output | 200-Mbps differential outputs with 247–454 mV VOD(SS) and 1.125–1.375 V VOC(SS) - meets ANSI TIA/EIA-644 LVDS standard for noise-immune high-speed data transfer. |
| RD / CS / BUS_BUSY (Pins 47, 1, 48) | CMOS read control & status | RD initiates data read; CS enables LVDS outputs; BUS_BUSY indicates active conversion - provides handshake capability for FPGA or microcontroller host interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-latency operation at 2 MSPS | Enables real-time feedback in closed-loop control without pipeline delay - critical for motor drive current sensing and adaptive power supply regulation. |
| Dual LVDS interface modes | Supports both daisy-chain (MODE_C/D = 0) and cascade (MODE_C/D = 1) configurations - allows scalable multi-ADC synchronization with single controller. |
| Configurable 16-/8-bit data frame | BYTE pin selects 16-clock (full word) or 8-clock (byte-split) frame - optimizes FPGA resource usage and simplifies deserialization logic. |
| Nap mode power reduction | Reduces supply current from 64 mA to 25 mA during idle conversion cycles - extends operational life in battery-powered portable diagnostics equipment. |
| Internal reference with buffer | 4.096-V reference with 10 µA source capability and 0.6 mV line regulation - eliminates need for external reference IC and associated decoupling complexity. |

FAQ
What is the absolute maximum input voltage range for ADS8413IBRGZRG4?
The ADS8413IBRGZRG4 specifies an absolute maximum analog input voltage range of –0.3 V to (+VA + 0.3 V) relative to AGND, with +VA rated up to 7 V. For normal operation, the unipolar differential input span is –4 V to +4 V using the internal 4.096-V reference, and the common-mode voltage must be maintained at VREF/2 ± 0.2 V. Exceeding these limits risks permanent damage per the datasheet's absolute maximum ratings table.
Does ADS8413IBRGZRG4 support external reference operation?
Yes, ADS8413IBRGZRG4 supports external reference operation via the REFIN pin (Pin 13), which accepts 3.9 V to 4.2 V. When using an external reference, REFOUT (Pin 14) must remain unconnected from REFIN, and the internal reference is disabled. The device retains all specified performance metrics including ±2 LSB INL max and 92 dB SNR, provided the external reference meets required noise, drift, and load regulation specifications.
How does nap mode reduce power consumption in ADS8413IBRGZRG4?
In nap mode (enabled by pulling NAP pin high), ADS8413IBRGZRG4 reduces analog supply current from 64 mA to 25 mA during idle conversion cycles while retaining full functionality and wake-up readiness. This cuts power dissipation from 290 mW to 125 mW at 2 MSPS, delivering a 57% reduction ideal for portable medical devices or thermally constrained industrial modules where duty-cycled sampling is employed.
Can ADS8413IBRGZRG4 be used in daisy-chain configurations with more than two devices?
Yes, ADS8413IBRGZRG4 supports daisy-chain configurations of up to four devices operating at full 2 MSPS throughput with a 200-MHz LVDS clock. The first device uses LAT_Y/N = 0; subsequent devices use LAT_Y/N = 1. Timing margins are preserved via SYNC_O propagation (tpd1 = 11 + 0.5×tCLK ns) and BUS_BUSY handshaking, as validated in Figures 12 and 15 of the SLAS490 datasheet.
What is the purpose of the MODE_C/D pin on ADS8413IBRGZRG4?
The MODE_C/D pin (Pin 6) configures ADS8413IBRGZRG4 for either daisy-chain (MODE_C/D = 0) or cascade (MODE_C/D = 1) multi-device operation. In daisy-chain mode, BUS_BUSY falling edge occurs before LVDS outputs enter 3-state; in cascade mode, BUS_BUSY falls after SDO/SYNC_O go to 3-state - enabling deterministic bus arbitration in tightly synchronized systems with three or more ADCs.
