OPA4243 ® OPA ® 424 3 OPA ® 424 3 For most current data sheet and other product information, visit www.burr-brown.com Quad OPERATIONAL AMPLIFIER MicroPOWER, Single-Supply FEATURES DESCRIPTION ● MICRO-SIZE, TSSOP PACKAGE ● SINGLE-SUPPLY OPERATION The OPA4243 is a four-channel op amp specifically designed for high density, space-limited applications, such as LCD bias drivers, PCMCIA cards, batterypacks and portable instruments. In addition to small size, this part features wide output swing, very low quiescent current, and low bias current. Other features include unity gain stability and the best speed power ratio available. Power supplies in the range of 2.2V to 36V (±1.1V to ±18V) can be used. ● WIDE SUPPLY RANGE: 2.2V to 36V ● LOW QUIESCENT CURRENT: 45µA/chan ● WIDE BANDWIDTH: 430kHz ● WIDE INPUT/OUTPUT SWING APPLICATIONS ● LCD DISPLAY DRIVERS ● BATTERY POWERED SYSTEMS ● PORTABLE EQUIPMENT ● PCMCIA CARDS ● BATTERY PACKS AND POWER SUPPLIES ● CONSUMER PRODUCTS Each channel uses completely independent circuitry for lowest crosstalk and freedom from interaction, even when overloaded. In addition, the amplifier is free from output inversion when the inputs are driven to the rail. The OPA4243EA is supplied in the miniature TSSOP-14 surface mount package. Specifications apply from –40°C to +85°C. However, as the extensive typical performance curves indicate, the OPA4243 can be used over the full –55°C to +125°C range. A SPICE macromodel is available for design analysis.

Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. (2) Inputs are diode-clamped to the supply rails and should be current-limited to 10mA or less if input voltages can exceed rails by more than 0.3V. (3) Short-circuit to ground, one amplifier per package.

The OPA4243 is unity-gain stable and suitable for a wide range of general-purpose applications. The power supply pins should be bypassed with 0.01µF ceramic capacitors. INPUT PROTECTION Rail-to-rail input signals will not cause damage or invert the output of the OPA4243. To protect against ESD and excessive input voltage (beyond the supply rails) the OPA4243 includes diodes from the input terminals to the power supply rails. Normally, these diodes are reversed biased and have negligible effect on circuit operation. However, if the input voltage is allowed to exceed the supply voltages by enough to forward bias these diodes (generally, 0.3V to 0.6V) excessive input current could flow. If this condition could occur (for example, if an input signal is applied when the op amp supply voltage is zero), care should be taken to limit the input current to less than 10mA to avoid damage. An input signal beyond the supplies, with power applied, can cause an unexpected output inversion. OPERATING VOLTAGE The OPA4243 can operate from single supply (2.2V to 36V) or dual supplies (±1.1V to ±18V) with excellent performance. Unlike most op amps which are specified at only one supply voltage, the OPA4243 is specified for real world applications; a single set of specifications applies throughout the 2.6V to 36V supply range. This allows the designer to have the same assured performance at any supply voltage within this range. In addition, many key parameters are guaranteed over the specified temperature range, –40°C to +85°C. Most behaviors remain unchanged throughout the full operating voltage range. Parameters, which vary significantly with operating voltage or temperature, are shown in the typical performance curves. ® 7 OPA4243 PACKAGE OPTION ADDENDUM www.ti.com 10-Dec-2020 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Pins Package Drawing Qty Eco Plan (2) Lead finish/ Ball material MSL Peak Temp Op Temp (°C) Device Marking (3) (4/5) (6) OPA4243EA/250 ACTIVE TSSOP PW 14 250 RoHS & Green NIPDAU Level-3-260C-168 HR -40 to 85 OPA 4243EA OPA4243EA/2K5 ACTIVE TSSOP PW 14 2500 RoHS & Green NIPDAU Level-3-260C-168 HR -40 to 85 OPA 4243EA (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
