Product details
Overview
RI-ACC-008B-00 from Texas Instruments is an antenna tuning module for 134.2 kHz HDX/FSK RFID systems, forming the resonant circuit with external antennas and enabling up to 120 m reader-to-antenna distance via twinax cable. It supports 8–80 µH antenna inductance range, delivers up to 380 Vpeak resonance voltage, and operates from –25°C to +70°C in industrial access control and asset tracking systems.
For engineers reviewing the RI-ACC-008B-00 datasheet, RI-ACC-008B-00 pinout, RI-ACC-008B-00 application, or RI-ACC-008B-00 equivalent, key selection factors include its 8–80 µH tunable inductance range, 380 Vpeak resonance capability, twinax-cable interface compatibility with RI-RFM-008B, and operation within harsh industrial environments (–25°C to +70°C, <97% non-condensing humidity).
Technical Context
The RI-ACC-008B-00 functions as a passive resonant tuning board that interfaces between the RI-RFM-008B RF power module and external LF antennas. It does not contain active circuitry but provides precise LC resonance tuning at 134.2 kHz using configurable capacitors matched to antenna inductance.
It enables extended-range HF/LF RFID deployment by decoupling antenna placement from the RF driver module - supporting symmetrical twinax cabling up to 120 meters while maintaining signal integrity and peak resonance voltage up to 380 Vpeak, dependent on configured inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency | 134.2 kHz - precisely matches TI HDX/FSK transponder carrier frequency for reliable energizing and backscatter communication. |
| Antenna Tuning Range | 8 µH to 80 µH - accommodates TI gate antennas (RI-ANT-G01E/G02E/G04E) and stick antennas (RI-ANT-S01C/S02C) without redesign. |
| Resonance Voltage | Max. 380 Vpeak - sustains high-field strength at extended distances, critical for reliable transponder wake-up beyond 50 m. |
| Operating Temp | –25°C to +70°C - validated for uncontrolled industrial enclosures and outdoor access control housings. |

| Dimensions | 115 × 70 × 27 mm ±1 mm - compact form factor fits standard DIN-rail or panel-mount RFID controller enclosures. |
Pinout & Package
RI-ACC-008B-00 is a passive tuning board with no active IC pins; it features two RF input terminals (IN+ / IN−) and two antenna output terminals (ANT+ / ANT−), designed for direct connection to symmetrical twinax cable from RI-RFM-008B and to external loop antennas. No semiconductor pinout applies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Differential RF input (positive) | Accepts balanced 134.2 kHz drive signal from RI-RFM-008B via twinax; requires impedance-matched termination. |
| IN− | Differential RF input (negative) | Completes differential path; maintains common-mode rejection and minimizes EMI over long cable runs. |
| ANT+ | Antenna resonant node (+) | Connects to one end of external antenna coil; forms tuned LC tank with onboard capacitors. |
| ANT− | Antenna resonant node (−) | Connects to other end of antenna coil; defines reference for resonant current loop and voltage peak distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Extended antenna induction range | Enables 120 m separation between reader module (RI-RFM-008B) and antenna - eliminates need for local RF electronics at gate or container entry points. |
| Tunable inductance support | Validated across 8–80 µH - covers TI's full portfolio of gate and stick antennas without custom capacitor rework. |
| High-voltage resonance capability | Rated for 380 Vpeak - maintains sufficient magnetic field strength (>1.5 A/m) at 100+ m distance for reliable HDX transponder activation. |
| Industrial environmental rating | Operates continuously at –25°C to +70°C with 97% non-condensing humidity - suitable for unheated outdoor kiosks and landfill site readers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar antenna tuning applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-ACC-008B-30 | Same electrical specs and mechanical footprint; differs only in packaging and obsolescence status (ACTIVE vs OBSOLETE). | Identical use in RI-RFM-008B-based systems; supports same antenna models and twinax cabling. | Select RI-ACC-008B-30 for new designs - identical performance with guaranteed supply continuity. |
| RI-ACC-007B-00 | Supports narrower 10–50 µH range; max resonance voltage 320 Vpeak; smaller 95 × 60 × 22 mm package. | Limited to shorter-range (<70 m) or lower-inductance antenna deployments; unsuitable for RI-ANT-G04E or 120 m twinax runs. | Choose only if legacy system reuse or space-constrained mounting dictates smaller size and reduced inductance range. |
Compared with RI-ACC-008B-00, RI-ACC-008B-30 offers identical functionality and fit, making it the direct replacement for new production; RI-ACC-007B-00 trades range and voltage headroom for compactness, limiting deployment flexibility in high-performance remote-antenna systems.

FAQ
What is the primary function of the RI-ACC-008B-00 in a TI RFID system?
The RI-ACC-008B-00 is a passive antenna tuning module that forms the resonant LC circuit with external 134.2 kHz antennas, enabling extended-range operation up to 120 meters when paired with the RI-RFM-008B RF power module. It does not contain active components but provides precise capacitance matching for 8–80 µH antenna inductances, ensuring optimal energy transfer and transponder activation. Its role is strictly analog resonance tuning - not signal processing or modulation.
Can RI-ACC-008B-00 be used with antennas outside the TI portfolio?
Yes, RI-ACC-008B-00 can be used with third-party 134.2 kHz antennas provided their inductance falls within the validated 8–80 µH range and they are rated for ≥380 Vpeak resonance voltage. However, TI only certifies performance with its own antennas (e.g., RI-ANT-G01E, RI-ANT-S02C). For non-TI antennas, users must verify impedance match, voltage handling, and thermal derating under continuous duty - especially at extended cable lengths.
Is RI-ACC-008B-00 still in production, and what are the implications for new designs?
No - TI lists RI-ACC-008B-00 as OBSOLETE per its packaging addendum. New designs should use RI-ACC-008B-30, which shares identical electrical and mechanical specifications but carries ACTIVE status. RI-ACC-008B-00 remains available through Aetrix Electronics for legacy repair and maintenance, with traceable sourcing and documented lifecycle support, but no future manufacturing assurance.
What cable type and maximum length is supported between RI-ACC-008B-00 and RI-RFM-008B?
RI-ACC-008B-00 requires a symmetrical shielded twinax cable - specifically designed for balanced 134.2 kHz RF transmission - with maximum verified length of 120 meters. Cable impedance, capacitance per meter, and shield coverage directly impact resonance voltage and read reliability; TI specifies twinax (not coax or twisted pair) to maintain common-mode noise rejection and minimize RF loss over distance.
Does RI-ACC-008B-00 require external power or configuration?
No, RI-ACC-008B-00 is a fully passive component with no power input, control interface, or configuration options. It contains fixed or manually selected capacitors for inductance tuning and relies entirely on the RF drive signal from RI-RFM-008B. All operational parameters - including resonance frequency and voltage - are determined by the combined LC values of RI-ACC-008B-00 and the connected antenna, with no user-adjustable settings or firmware.
