TLV2620IP - 11 MHz RRO CMOS Op Amp with Shutdown | Texas Instruments
N.º da peça: TLV2620IP ✓ AtivoTLV2620IP Visão geral
What is a rail-to-rail operational amplifier? A rail-to-rail (RRO) input and output amplifier is an operational amplifier whose input common-mode range and output swing extend to the positive and negative supply rails, so it can process signals from 0 V up to the full supply voltage without clipping. In the device hierarchy an operational amplifier is a linear amplifier IC within the broader amplifier and analog signal-chain family, and the TLV2620 family belongs to TI's low-power, wide-bandwidth single-supply op amp line.
Key features of the TLV2620IP include an 11 MHz gain-bandwidth product for single-supply operation up to 5.5 V, rail-to-rail input and output swing, an integrated shutdown control for supply-current management, and a CMOS input stage that offers low input bias current with high input impedance. The single-amplifier configuration keeps the footprint small while still supporting standard feedback networks and unity-gain stable operation for buffer and gain stages.
Technically, the amplifier operates from a single positive supply, so the negative supply pin is tied to ground. Its wide bandwidth makes it suitable for filtering, buffering and signal-conditioning blocks rather than only for slow precision DC measurement. Because it is a CMOS design, the device suits battery and energy-harvesting systems where leakage current matters, while the shutdown pin allows the rail to be collapsed entirely when the node is not being sampled.
Typical applications include portable sensor signal conditioning, low-side current-sense amplification, audio and communication line-driver preambles, battery-powered monitor front ends, and general-purpose buffering inside test and measurement equipment.
When designing with the TLV2620IP, remember that the shutdown pin is a logic input referenced to the supply rail, not ground, so drive it from a rail-compatible signal and make sure it is never left floating. Also respect the maximum total supply voltage of 5.5 V and provide adequate decoupling close to the supply pins.
This page consolidates the key electrical characteristics, an at-a-glance comparison against pin-compatible drop-in alternatives, and practical design notes covering layout, decoupling and shutdown control, giving engineers the guidance needed to qualify the part before it reaches schematic review.

Aplicações típicas
TLV2620IP é adequado para 6 aplicaçãos: Portable Sensor Signal Conditioning, Battery-Powered Monitor and Metering, Industrial Sensor Node, Audio and Communication Line Buffering, Medical and Laboratory Instrumentation, General-Purpose Buffering and Filtering.
Portable Sensor Signal Conditioning
The TLV2620IP fits low-power sensor front ends where the sensor output is close to 0 V or near the supply rail. Its rail-to-rail input common-mode range means a resistive divider or thermistor referenced to ground does not need mid-supply biasing, and the 11 MHz gain-bandwidth product gives enough loop gain for a modest closed-loop gain stage at sensor update rates. The CMOS input stage avoids the microamp-level bias currents of bipolar amplifiers, which matters when the divider impedance is in the hundreds of kiloohms. Use the shutdown pin to disable the amplifier between conversion windows and cut average supply current in a coin-cell powered node.

Battery-Powered Monitor and Metering
In portable metering equipment the TLV2620IP combines a 5.5 V maximum supply with rail-to-rail operation, so a single lithium cell or a 3.3 V rail can drive it directly without level shifting. The dedicated shutdown input lets the designer park the amplifier between measurement intervals, reducing leakage-driven supply current that dominates the standby budget of battery devices. With an 11 MHz gain-bandwidth product the same amplifier can also serve the anti-alias filter in front of an ADC, avoiding the need for a second active device. Keep the supply decoupling capacitor within a few millimetres of the supply pins to keep the rail clean during the switching transitions of the shutdown event.

Industrial Sensor Node
Industrial transducers frequently present small signals riding on a slow-moving common-mode level, and the TLV2620IP handles this well because the rail-to-rail input range tolerates input voltages that approach either supply limit. The single 5.5 V ceiling means the amplifier fits 24 V systems when paired with an upstream divider or protection network, and the through-hole 8-PDIP package is convenient for leaded assembly and for prototypes built with hand-soldered sockets. The 9.5 V/us slew rate gives comfortable headroom for driving the input capacitance of long shielded sensor cables. Confirm the minimum supply voltage and the input protection limits against the datasheet before deploying in a 24 V loop.
Recomendado
Audio and Communication Line Buffering
The TLV2620IP serves as a line-level buffer or impedance driver in audio and communication equipment, where the rail-to-rail output swing preserves headroom on low-voltage rails that would clip a non-rail-to-rail amplifier. The 9.5 V/us slew rate is adequate for driving typical line-level impedances and short cable runs without visible distortion on standard audio bandwidth signals. Because it is a single amplifier in a DIP package, designers frequently use it in the gain-flattening and summing stages between a mixer and an output driver. Keep input and feedback resistors physically close to the device to limit parasitic pickup, which matters more in unbalanced audio paths than in purely differential instrumentation circuits.
Recomendado
Medical and Laboratory Instrumentation
In laboratory and patient-adjacent instrumentation the TLV2620IP is used in the input stage of buffer amplifiers, active filters and comparators built around low-level sensors. The CMOS architecture provides high input impedance so the instrument does not load the transducer, and the wide bandwidth supports filtering stages that shape the signal before conversion. Because the part is a single amplifier in a through-hole package, it can be socketed on a prototype board and swapped quickly during bench bring-up, which shortens the iteration cycle compared with surface-mount only options. Review the medical device qualification status and the operating temperature limits in the datasheet before committing it to a patient-connected design.
Recomendado
General-Purpose Buffering and Filtering
The TLV2620IP works as a unity-gain buffer, active filter element or comparator front end in general-purpose analog blocks, and the 8-PDIP footprint makes it a familiar building block on educational and legacy-compatible boards. With 11 MHz of gain-bandwidth product, a second-order Sallen-Key low-pass filter built around this amplifier retains usable shape well into the audio and low ultrasonic range, and the same stage can buffer a high-impedance source into a downstream ADC. The shutdown pin is also handy in multiplexer systems, where unused amplifiers are disabled to prevent cross-channel loading and reduce supply current across a large sensor array.

Notas de projeto
The TLV2620IP is a single-supply device with a 5.5 V maximum total supply rating, so the V- pin goes to ground and V+ must never exceed that limit, including transients. Place a 0.1 uF ceramic bypass capacitor directly at pins 7 and 4, and add a bulk capacitor (1 uF to 10 uF, low ESR) close to the supply pins. Because the shutdown pin is referenced to V+, pull it to V+ with a resistor when shutdown is not used, and drive it from a rail-compatible logic signal otherwise; leaving it floating gives an indeterminate operating state.
For an 11 MHz device in a DIP-8 package, keep the feedback network and input routing short to avoid parasitic feedback. Keep the inverting input trace (pin 2) away from the output trace (pin 6) and from the supply pins, and route the non-inverting input (pin 3) as a short, guarded trace to the source. On a through-hole board, add a ground plane on the opposite layer to shorten return currents and reduce coupling from the shutdown net (pin 5) into the sensitive input node.
With an 11 MHz gain-bandwidth product and roughly 9.5 V/us slew rate, the amplifier has ample bandwidth for audio-band and low-ultrasonic signals, but stability at high closed-loop gains depends on the feedback resistor and capacitor values chosen. If a noise-gain stage at 10x or more shows peaking or ringing, add a small capacitor in parallel with the feedback resistor to reduce the noise gain at high frequency. Also check the capacitive load presented by long shielded cables and add an isolation resistor (50 ohm to 100 ohm) between the amplifier output and the cable if overshoot appears on the scope.
The most common mistake when substituting this part is treating the 8-SOIC variant TLV2620IDR as a footprint match; SOIC-8 and 8-PDIP have different lead spacing and cannot share a land pattern. The second common error is assuming the shutdown pin of the TLV2620 matches the pin assigned to shutdown on a competing DIP amplifier such as the MCP6023-E/P, which has no shutdown pin at all - that net must be tied to the active state and the board reworked. Finally, check the pin table in the manufacturer data sheet rather than a generic DIP-8 op amp drawing, since pin 5 carries the shutdown function on this family.
