OPA551

OPA552

High-Voltage, High-Current

OPERATIONAL AMPLIFIERS

DESCRIPTION

The OPA551 and OPA552 are low cost op amps with high-

voltage (60V) and high-current (200mA) capability.

The OPA551 is unity-gain stable and features high slew rate

(15Vµs) and wide bandwidth (3MHz). The OPA552 is

optimized for gains of 5 or greater, and offers higher speed

with a slew rate of 24V/µs and a bandwidth of 12MHz. Both

are suitable for telephony, audio, servo, and test applications.

These laser-trimmed, monolithic integrated circuits provide

excellent low-level accuracy along with high output swing.

High performance is maintained as the amplifier swings to

its specified limits.

The OPA551 and OPA552 are internally protected against

over-temperature conditions and current overloads. The

thermal shutdown indicator “flag” provides a current output

to alert the user when thermal shutdown has occurred.

The OPA551 and OPA552 are available in DIP-8 and

SO-8 packages, as well as a DDPAK-7 surface-mount

plastic power package. They are specified for operation

over the extended industrial temperature range, –40°C to

+125°C.

APPLICATIONS INFORMATION Figure 1 shows the OPA551 connected as a basic noninverting amplifier. The OPA551 can be used in virtually any op amp configuration. OPA552 is designed for use in configurations with gains of 5 or greater. Power supply terminals should be bypassed with 0.1µF capacitors, or greater, near the power supply pins. Be sure that the capacitors are appropriately rated for the power supply voltage used. The OPA551 and OPA552 can supply output currents up to 200mA with excellent performance.
PAGE 10
POWER SUPPLIES The OPA551 and OPA552 may be operated from power supplies of ±4V to ±30V, or a total of 60V with excellent performance. Most behavior remains unchanged throughout the full operating voltage range. Parameters that vary significantly with operating voltage are shown in the Typical Performance Curves. For applications that do not require symmetrical output voltage swing, power supply voltages do not need to be equal.

power supplies, this creates an internal dissipation of 11.4W. This far exceeds the maximum rating and is not recommended. If operation in this region is unavoidable, use the DDPAK with a heat sink. SAFE OPERATING AREA—8-PIN DIP 1000 IO (mA) 125°C 10 85°C 1 0.1 10 Power dissipated in the OPA551 or OPA552 will cause the junction temperature to rise. For reliable operation, the junction temperature should be limited to +125°C.

CAPACITIVE LOADS The dynamic characteristics of the OPA551 and OPA552 have been optimized for commonly encountered gains, loads, and operating conditions. The combination of low closedloop gain and capacitive load will decrease the phase margin and may lead to gain peaking or oscillations. Figure 7 shows a circuit that preserves phase margin with capacitive load. Figure 8 shows the small-signal step response for the circuit in Figure 7. Consult Application Bulletin AB-028 for more information.
PAGE 13
INPUT PROTECTION The OPA551 and OPA552 feature internal clamp diodes to protect the inputs when voltages beyond the supply rails are encountered. However, input current should be limited to 5mA. In some cases, an external series resistor may be required. Many input signals are inherently current-limtied, therefore, a limiting resistor may not be required. Please consider that a “large” series resistor, in conjunction with the input capacitance, can affect stability.
PAGE 14
OFFSET VOLTAGE ERROR CALCULATION The offset voltage (VOS) of the OPA51 and OPA552 is specified with a ±30V power supply and the commonmode voltage centered between the supplies (VS/2 = 0V). Additional specifications for power supply rejection and common-mode rejection are provided to allow the user to easily calculate worst-case excepted offset under the conditions of a given application. Power Supply Rejection Ratio (PSRR) is specified in µV/V.
