Product details
Overview
ADA4310-1ARHZ-R7 from Analog Devices is a dual, current-feedback operational amplifier optimized as a high-current line driver with shutdown control. It delivers 190 MHz −3 dB bandwidth at G = +5, 820 V/µs slew rate into 50 Ω, and 20.4 V p-p differential output swing on 12 V supply - enabling broadband twisted-pair and power-line communications transmission.
For engineers reviewing the ADA4310-1ARHZ-R7 datasheet, ADA4310-1ARHZ-R7 pinout, ADA4310-1ARHZ-R7 application, or ADA4310-1ARHZ-R7 equivalent, key selection criteria include its four-mode CMOS-compatible power-down control (PD0/PD1), thermally enhanced 10-lead MSOP package with exposed ground paddle, and verified performance in I/Q channel amplification and PLC driver stages.
Technical Context
The ADA4310-1ARHZ-R7 implements a current-feedback architecture with transimpedance open-loop gain of 14 MΩ (RLOAD = 50 Ω) and 35 MΩ (RLOAD = 100 Ω). Its input stage features 500 kΩ input resistance and ±2 µA to +6 µA input bias currents, supporting stable operation with low-impedance feedback networks.
Power management is implemented via two CMOS-level pins (PD0, PD1) enabling four discrete operating modes: full power (7.6 mA/amp), medium power (5.6 mA/amp), low power (3.9 mA/amp), and shutdown (0.65 mA/amp), with output transitioning to high-impedance state only in shutdown mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| −3 dB Bandwidth | 190 MHz at G = +5, enabling baseband-to-VHF signal amplification without gain-bandwidth trade-off |
| Slew Rate | 820 V/µs into 50 Ω, supporting fast transient response for high-fidelity video and communication waveforms |
| Differential Output Swing | 20.4 V p-p into 100 Ω load on 12 V supply, sufficient for ARB and PLC line-driving compliance |
| Harmonic Distortion | −95 dBc at 1 MHz, ensuring minimal spectral regrowth in narrowband PLC and I/Q applications |
| Supply Range | +5 V to +12 V single supply only (due to exposed paddle tied to GND in RH-10-1 package) |
| Quiescent Current | 0.65 mA/amp in shutdown mode, reducing system standby power by >90% vs. full-power operation |
| Operating Temperature | −40°C to +85°C extended industrial range, validated for outdoor home networking and industrial PLC deployments |
Pinout & Package
ADA4310-1ARHZ-R7 is packaged in a thermally enhanced 10-lead Mini Small Outline Package with Exposed Pad (MINI_SO_EP, package option RH-10-1). The exposed paddle must be electrically connected to GND for proper operation and thermal conduction; failure to do so renders the device inoperable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+VS) | Positive power supply input | Accepts +5 V to +12 V; no negative supply connection - single-supply only in this package variant |
| 2 (NIC) | No internal connection | Must remain unconnected; no routing or grounding required |
| 3 (OUT A) | Amplifier A output | High-current, low-impedance output capable of driving 50 Ω or 100 Ω loads differentially |
| 4 (−IN A) | Amplifier A inverting input | Current-feedback node; requires low-inductance feedback resistor placement for stability |
| 5 (+IN A) | Amplifier A noninverting input | High-impedance input (500 kΩ); used for reference biasing in single-supply configurations |
| 6 (PD0) | Power-down control input | CMOS-compatible logic input; sets power mode jointly with PD1 (see Table 7 in datasheet) |
| 7 (PD1) | Power-down control input | CMOS-compatible logic input; defines one of four power states with PD0 |
| 8 (+IN B) | Amplifier B noninverting input | Independent high-Z input for second channel; supports I/Q or dual-line driver topologies |
| 9 (−IN B) | Amplifier B inverting input | Current-feedback node for Channel B; requires matched layout to Channel A for crosstalk control |
| 10 (OUT B) | Amplifier B output | Functionally identical to OUT A; enables true dual-channel line driving without external buffering |
| Exposed Paddle | Ground (electrical connection required) | Serves as primary thermal path and electrical reference for PD pins; must be soldered to solid GND plane |
Key Features
| Feature | Design Value |
|---|---|
| Four-mode power control | Configurable per-channel quiescent current (0.65–7.6 mA/amp) via CMOS-level PD0/PD1 pins |
| High-output-current drive | Delivers >200 mA peak per channel into 50 Ω, eliminating need for external buffer stages in line drivers |
| Low distortion at high frequency | −69 dBc at 10 MHz ensures clean spectral content for wideband PLC and video transmission |
| Thermally optimized MSOP | θJA = 44°C/W with exposed paddle grounded - enables sustained full-power operation at +85°C ambient |
| Single-supply compatibility | Operates from +5 V to +12 V with rail-to-rail input common-mode range up to VS − 1.2 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4311-1ARHZ-R7 | Single-channel version; identical bandwidth (190 MHz), slew rate (820 V/µs), and power-down architecture | Used where space or cost constraints favor single-channel implementation; requires two units for dual-path designs | Select when only one high-current driver channel is needed and PCB area is constrained |
| THS3202DGN | Higher slew rate (3000 V/µs) but lower −3 dB bandwidth (120 MHz at G = +5); no integrated power-down pins | Lacks CMOS-compatible shutdown control; requires external logic and bias circuitry for power management | Choose only if extreme slew rate dominates over integrated power control and distortion performance |
Compared with ADA4310-1ARHZ-R7, ADA4311-1ARHZ-R7 reduces channel count but retains identical per-channel specs and power modes, whereas THS3202DGN trades programmable power efficiency for raw speed and lacks native shutdown functionality - making ADA4310-1ARHZ-R7 uniquely suited for dual-channel, energy-aware broadband line driving.

FAQ
What is the maximum supply voltage for ADA4310-1ARHZ-R7?
The ADA4310-1ARHZ-R7 supports a single positive supply from +5 V to +12 V. Its 10-lead MINI_SO_EP package (RH-10-1) ties the exposed thermal pad to GND, precluding dual-supply operation. Absolute maximum rating is 12 V; exceeding this risks permanent damage per Absolute Maximum Ratings Table 2.
Does ADA4310-1ARHZ-R7 support dual-supply operation?
No. ADA4310-1ARHZ-R7 is configured for single-supply use only due to its MINI_SO_EP package construction: the exposed paddle serves as both thermal path and GND reference, and Pin 1 (+VS) is the sole supply input. For dual-supply applications, the 16-lead LFCSP variant (e.g., ADA4310-1ACPZ-R7) must be selected.
How does the power-down function work on ADA4310-1ARHZ-R7?
ADA4310-1ARHZ-R7 uses two CMOS-compatible control pins (PD0 and PD1) to select among four power states: full power (7.6 mA/amp), medium (5.6 mA/amp), low (3.9 mA/amp), and shutdown (0.65 mA/amp). In shutdown, outputs enter high-impedance state - confirmed in Power Modes Table 7 and General Description section.
What is the recommended feedback resistor value for ADA4310-1ARHZ-R7?
The datasheet specifies 499 Ω as the recommended feedback resistor for ADA4310-1ARHZ-R7 across common gains (e.g., G = +5 yields 190 MHz bandwidth). Using lower values risks instability and peaking; higher values reduce bandwidth - both effects documented in Feedback Resistor Selection section and Table 6.
Is thermal pad connection mandatory for ADA4310-1ARHZ-R7?
Yes. The exposed thermal pad on ADA4310-1ARHZ-R7 must be electrically connected to GND. Notes in Figure 1 and Pin Configuration section explicitly state "THE EXPOSED PAD MUST BE CONNECTED TO GROUND (ELECTRICAL CONNECTION REQUIRED)" - omission causes functional failure and thermal runaway.
