Product details

Overview

ADA4310-1ACPZ-R7 from Analog Devices is a dual, current-feedback operational amplifier optimized as a high-current line driver for broadband signal distribution. 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 single supply - enabling robust driving of twisted-pair, PLC, or video lines in home networking and ARB systems.

For engineers reviewing the ADA4310-1ACPZ-R7 datasheet, ADA4310-1ACPZ-R7 pinout, ADA4310-1ACPZ-R7 application, or ADA4310-1ACPZ-R7 equivalent, key selection criteria include power-mode configurability (PD0/PD1), thermal pad grounding requirements, differential output capability, and distortion performance across 1–20 MHz under varying load and gain conditions.

Technical Context

The ADA4310-1ACPZ-R7 implements a current-feedback architecture with transimpedance open-loop gain (14 MΩ at 50 Ω load), enabling near-constant bandwidth vs. gain behavior. Its dual amplifiers share independent CMOS-compatible PD0/PD1 control pins to select among four discrete quiescent current states: full power (7.6 mA/amp), medium (5.6 mA/amp), low (3.9 mA/amp), and shutdown (0.65 mA/amp).

It operates from ±2.5 V to ±6 V dual supply or +5 V to +12 V single supply, with output impedance <1 Ω below 10 MHz in active mode and >1 kΩ in shutdown. The exposed thermal pad on the LFCSP package is electrically isolated and must be connected to PCB ground for thermal management - unlike the MSOP variant where it serves as −VS reference.

Key Specifications

Parameter	Value and Actual Design Meaning
−3 dB Bandwidth	190 MHz at G = +5, 140 MHz in medium-power mode - supports wideband baseband and IF signal distribution without gain-dependent bandwidth collapse.
Slew Rate	820 V/µs into 50 Ω - enables clean 2 V p-p, 10 MHz sine wave reproduction with minimal slewing distortion.
Differential Output Swing	20.4 V p-p into 100 Ω on 12 V supply - sufficient headroom for high-fidelity line driving in PLC and video applications.
Harmonic Distortion	−95 dBc at 1 MHz, −69 dBc at 10 MHz (2 V p-p, 50 Ω) - meets spectral purity requirements for ARB and I/Q channel amplification.
Quiescent Current	0.65 mA/amp in shutdown, 3.9–7.6 mA/amp adjustable - allows dynamic power scaling in battery-sensitive or thermally constrained designs.
Input Voltage Noise	2.85 nV/√Hz at 100 kHz - preserves SNR in high-gain front-end stages before ADC or mixer interfaces.
Power Supply Range	+5 V to +12 V single supply or ±2.5 V to ±6 V dual supply - supports flexible integration with legacy and modern mixed-signal subsystems.

Pinout & Package

The ADA4310-1ACPZ-R7 uses a thermally enhanced 4 mm × 4 mm, 16-lead LFCSP (CP-16-23) with an electrically isolated exposed thermal pad that must be soldered to a PCB ground plane for thermal conduction. Unlike the MSOP variant, this package provides dedicated −VS (Pin 7) and +VS (Pin 14) pins, enabling true dual-supply operation.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1, 5, 6, 12, 15	NIC	No internal connection - must remain unconnected; no routing or grounding required.
Pin 2	−IN A	Inverting input of Amplifier A - high-impedance node requiring matched trace length and guard ring in current-feedback layout.
Pin 3	+IN A	Noninverting input of Amplifier A - referenced to VMID (AVDD/2) in single-supply biasing schemes.
Pin 4	GND	Analog ground reference - low-inductance connection to solid ground plane essential for PSR and CMR integrity.
Pin 7	−VS	Negative supply input - enables dual-supply operation; not present in MSOP variant.
Pin 8	PD0	Power-down control logic input - CMOS-level compatible (0/3 V); sets power mode with PD1.
Pin 9	PD1	Power-down control logic input - paired with PD0 to select full/medium/low/shutdown modes.
Pin 10	+IN B	Noninverting input of Amplifier B - independently configurable for I/Q or differential channel use.
Pin 11	−IN B	Inverting input of Amplifier B - symmetrical layout with Pin 2 critical for crosstalk minimization.
Pin 13	OUT B	Amplifier B output - capable of 20.4 V p-p differential swing into 100 Ω when paired with OUT A.
Pin 14	+VS	Positive supply input - decoupled with 0.1 µF MLCC ≤3 mm from pin per layout guidelines.
Pin 16	OUT A	Amplifier A output - forms differential pair with OUT B; requires matched termination to preserve balance.

Key Features

Feature	Design Value
Four-step power management	Configurable via PD0/PD1 logic: full (7.6 mA/amp), medium (5.6 mA/amp), low (3.9 mA/amp), or shutdown (0.65 mA/amp) - enables real-time thermal and power budget control.
Current-feedback architecture	190 MHz flat bandwidth up to G = +5 with 820 V/µs slew rate - eliminates gain-bandwidth trade-off typical of voltage-feedback op amps.
Dual-channel isolation	−90 dB typical crosstalk at 10 MHz - ensures independent operation of I/Q or differential channels without intermodulation.
High-output-current drive	Delivers >100 mA peak into 50 Ω loads - sustains 20.4 V p-p differential swing on 12 V supply without clipping or thermal foldback.
LFCSP thermal design	63 °C/W θJA on JEDEC 4-layer board - enables >2 W continuous dissipation with proper ground-pad soldering and copper area.

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
THS3202DGN	Single-channel, 1.8 GHz bandwidth, 4000 V/µs slew rate, no integrated power-down control.	Higher bandwidth but lacks dual-channel integration and programmable quiescent current - requires external logic for power sequencing.	Preferred for ultra-wideband (>500 MHz) single-ended applications where power management is handled externally.
LMH6554MA	Dual-channel, 2.8 GHz bandwidth, 5200 V/µs slew rate, fixed 22 mA/amp quiescent current, no PD pins.	Superior speed and drive strength but consumes >3× more power and offers no low-power modes - unsuitable for thermally constrained or battery-backed systems.	Selected when maximum bandwidth and output current outweigh thermal and power efficiency requirements.

Compared with THS3202DGN and LMH6554MA, the ADA4310-1ACPZ-R7 uniquely balances 190 MHz bandwidth, dual-channel integration, and four-step power management in a compact LFCSP - making it optimal for space- and power-sensitive broadband line drivers where thermal headroom is limited.

FAQ

What is the correct thermal pad connection for ADA4310-1ACPZ-R7?

The exposed thermal pad on the ADA4310-1ACPZ-R7 (LFCSP package) is electrically isolated and must be soldered to a PCB ground plane using ≥60% solder coverage. Unlike the MSOP variant, it has no electrical function beyond thermal conduction - failure to connect it degrades thermal resistance by >40%, risking junction temperature exceedance above 150°C under sustained load.

How does power-down mode affect the output state of ADA4310-1ACPZ-R7?

In power-down mode (PD1 = PD0 = high), the ADA4310-1ACPZ-R7 output terminals enter a high-impedance state with leakage <100 nA, isolating downstream circuitry. This is confirmed in Table 7 and Figure 17, where output impedance exceeds 1 kΩ above 100 kHz. The feature enables safe multiplexing or hot-swap operation without signal contention.

Can ADA4310-1ACPZ-R7 operate from a single +12 V supply?

Yes - the ADA4310-1ACPZ-R7 supports +5 V to +12 V single-supply operation. Its input common-mode range extends to within 1.2 V of the negative rail (GND), and output swing reaches +5.14 V and −5.17 V into 100 Ω, enabling 20.4 V p-p differential output. Biasing requires VMID = AVDD/2 (6 V) applied to +IN pins via resistive divider or low-noise reference.

What is the recommended feedback resistor value for ADA4310-1ACPZ-R7 at G = +5?

The datasheet specifies 499 Ω as the recommended feedback resistor for G = +5 configuration (Table 6). Using this value achieves the rated 190 MHz −3 dB bandwidth and optimal phase margin. Deviating below 499 Ω risks peaking and instability; exceeding it reduces bandwidth - e.g., 1 kΩ lowers bandwidth to 125 MHz per Table 6 test conditions.

Does ADA4310-1ACPZ-R7 support dual-supply operation?

Yes - the ADA4310-1ACPZ-R7 supports ±2.5 V to ±6 V dual supplies, enabled by dedicated −VS (Pin 7) and +VS (Pin 14) pins. This allows true bipolar signal handling with symmetric output swing and improved PSRR (−70 dB positive, −60 dB negative) versus single-supply mode. The MSOP variant lacks −VS and cannot operate in dual-supply mode.
