OPA2652U - 200MHz Dual Op Amp | Texas Instruments
부품 번호: OPA2652U ✓ 활성OPA2652U 개요
A voltage-feedback operational amplifier is a differential amplifier whose closed-loop behavior is set primarily by external feedback components. In the signal-chain hierarchy, the OPA2652U belongs to the operational-amplifier and analog-amplifier categories, where it provides high-bandwidth gain and signal conditioning between sensors, converters, filters, data converters, and output stages. Its differential input accepts bipolar signals, while its output stage must remain within the selected supply rails.
The principal features are a 200 MHz gain-bandwidth product, low 5.5 mA per-channel quiescent current, support for dual ±5 V supplies, support for single +6 V to +12 V operation, and 140 mA output-current capability. These characteristics suit applications that require more bandwidth than conventional low-cost amplifiers while retaining lower power consumption than many high-speed alternatives.
The OPA2652U uses a classical differential-input, voltage-feedback architecture. Its wide open-loop bandwidth allows it to maintain useful closed-loop gain over a wide frequency range, while the selected feedback network determines the actual gain and bandwidth. When used with resistive feedback, the circuit designer must account for parasitic capacitance, output loading, and the input/output voltage limits imposed by the supply configuration.
Typical uses include low-cost video amplification, communication-interface signal conditioning, analog measurement chains, active filtering, and general-purpose high-frequency amplification. The dual configuration can process two independent channels or implement one differential stage. Single-supply operation is useful in compact +6 V to +12 V systems, whereas ±5 V operation simplifies centered bipolar signal paths.
For reliable layout, keep feedback resistors close to the amplifier pins, use short ground returns, and place input and output decoupling capacitors near the device. Avoid long PCB traces that can add parasitic feedback and reduce stability margin. Account for output-current demand and the DC power dissipated by the amplifier when operating across a wide voltage span.

Low-Cost Video Signal Conditioning
OPA2652U fits low-cost video amplification because its 200 MHz gain-bandwidth product provides substantial bandwidth while the 140 mA output-current capability supports typical terminated video outputs. The amplifier can operate from ±5 V for centered bipolar video signals or from a single +6 V to +12 V rail when the circuit permits that output range. Use a feedback network designed for the intended gain and verify output swing, load termination, and stability at the selected video standard before production.
추천
Communications Interface Amplification
OPA2652U is suitable for communications-interface amplification when a compact, low-cost channel needs more bandwidth than general-purpose amplifiers. Its 200 MHz gain-bandwidth product supports moderate closed-loop gains, while 5.5 mA per channel of quiescent current keeps channel power in check. Place the amplifier near the driven line and terminate it according to the interface specification, while checking whether ±5 V is required or whether a single +6 V to +12 V implementation preserves the required signal levels.
추천
Active Analog Filtering
OPA2652U can implement active low-pass or band-pass sections in instrumentation and communications systems that require wider bandwidth than ordinary precision amplifiers provide. Its 200 MHz gain-bandwidth product gives design flexibility for moderate closed-loop gains, and its voltage-feedback topology works directly with resistor-and-capacitor filter networks. Select resistor and capacitor values against the closed-loop bandwidth, place feedback components close to the device, and verify noise, phase margin, and output-swing behavior over the full frequency range.
추천
Precision Measurement Front Ends
OPA2652U is useful in measurement front ends where sensor bandwidth is moderate but the amplifier must remain low-cost and reasonably low in quiescent consumption. The 5.5 mA per-channel quiescent current and dual amplifier configuration allow two signal paths in one 8-pin SOIC. For precision use, verify input offset, bias current, noise, common-mode range, and output swing for the selected grade. The 200 MHz gain-bandwidth product does not by itself establish DC precision, so sensor-level requirements still govern the final selection.
추천
Data Converter Interface Amplifiers
OPA2652U fits input and output conditioning around moderate-speed data converters because its 200 MHz gain-bandwidth product and 140 mA output-current capability offer more bandwidth and drive than low-frequency precision amplifiers. The ±5 V supply option can support converter signal swings that exceed a low-voltage rail, while the differential-input voltage-feedback architecture simplifies standard inverting and noninverting networks. Confirm converter logic levels, output impedance, settling requirements, and supply sequencing before choosing the amplifier configuration.
추천
General-Purpose Dual Signal Amplification
OPA2652U provides two independent voltage-feedback amplifier channels in one compact SOIC package for general-purpose instrumentation and control-board tasks. The 200 MHz bandwidth handles higher-frequency portions of a signal path, while the 5.5 mA per-channel quiescent current avoids the power burden of two separate high-speed amplifiers. Use independent feedback networks for dual-channel processing or configure the channels for a differential function, and verify signal polarity, common-mode range, grounding, and output swing on each implemented circuit.

설계 노트
Place the input, output, feedback, and bypass components directly beside their associated OPA2652U pins. Keep feedback-resistor networks short and connect the exposed ground return through a low-impedance plane. Long traces around a high-speed voltage-feedback amplifier can add parasitic capacitance and create unintended feedback. Use the manufacturer pinout and recommended layout when assigning PCB tracks so the 8-pin SOIC footprint remains reusable across valid drop-in candidates.
Calculate amplifier dissipation from the actual supply, output voltage, load current, and quiescent current before finalizing the power budget. For a linear amplifier, approximate output-stage dissipation as the voltage across the output transistor multiplied by load current, then add the quiescent contribution. Keep the operating point below the manufacturer maximum and verify junction-temperature rise on the intended PCB rather than assuming that the small SOIC package requires no thermal analysis.
Do not equate matching package and pin count with guaranteed interchangeability. Before substituting OPA2652U, confirm maximum supply voltage, input common-mode range, output swing, offset voltage, bias current, noise, slew rate, output-current capability, and stability at the intended closed-loop gain. Pay particular attention when moving between ±5 V and +6 V to +12 V operation because the usable input and output range can change with the selected supply configuration.
Choose the feedback network according to the required gain and signal bandwidth rather than using a generic resistor ratio. The 200 MHz gain-bandwidth product does not guarantee 200 MHz usable bandwidth at every gain, and excessive capacitive loading can reduce stability. For video, communications, or data-converter interfaces, terminate the output as required, control trace capacitance, and probe the completed design with suitable bandwidth and loading.
