FEATURES

DESCRIPTION

● MICRO-SIZE, MINIATURE PACKAGES

Single: SOT-23-5, SO-8

Dual: MSOP-8, SO-8

The OPA237 op amp family is one of Burr-Brown’s

MicroAmplifier series of miniature products. In addi-

tion to small size, these devices feature low offset

voltage, low quiescent current, low bias current, and a

wide supply range. Single, dual, and quad versions

have identical specifications for maximum design flex-

ibility. They are ideal for single supply, battery oper-

ated, and space-limited applications, such as PCMCIA

cards and other portable instruments.

Quad: SSOP-16

● LOW OFFSET VOLTAGE: 750µV max

● WIDE SUPPLY RANGE

Single Supply: +2.7V to +36V

Dual Supply: ±1.35V to ±18V

OPA237 series op amps can operate from either single

or dual supplies. When operated from a single supply,

the input common-mode range extends below ground

and the output can swing to within 10mV of ground.

Dual and quad designs feature completely indepen-

dent circuitry for lowest crosstalk and freedom from

interaction.

● LOW QUIESCENT CURRENT: 350µA max

● WIDE BANDWIDTH: 1.5MHz

APPLICATIONS

● BATTERY POWERED INSTRUMENTS

● PORTABLE DEVICES

● PCMCIA CARDS

Single, dual, and quad are offered in space-saving

surface-mount packages. The single version is available

in the ultra-miniature 5-lead SOT-23-5 and SO-8 sur-

face-mount. The dual version comes in a miniature

MSOP-8 and SO-8 surface-mount. The quad is avail-

able in an SSOP-16. The SSOP-16 has the same body

size as an SO-8 with 16 leads, while the MSOP-8 has the

same lead count as a SO-8 but half the size. The

SOT-23-5 is even smaller at one-fourth the size of an

SO-8. All are specified for –40°C to +85°C operation. A

macromodel is available for design analysis.

+5V supply with a 10kΩ load to V_S/2 is used. OPA237

series op amps remain stable with capacitive loads up to

4,000pF, if sinking current and up to 10,000pF, if sourcing

current. Furthermore, in single supply applications where

the load is connected to ground, the op amp is only

sourcing current, and as shown in Figure 1, can drive

10,000pF with output currents up to 1.5mA.

APPLICATIONS INFORMATION

OPA237 series op amps are unity-gain stable and suitable

for a wide range of general-purpose applications. Power

supply pins should be bypassed with 10nF ceramic capaci-

tors.

OPERATING VOLTAGE

OPA237 series op amps operate from single (+2.7V to

+36V) or dual (±1.35V to ±18V) supplies with excellent

performance. Most behavior remains unchanged through-

out the full operating voltage range. Parameters which

vary significantly with operating voltage are shown in

typical performance curves. Specifications are production

tested with +2.7V, +5V, and ±15V supplies.

OUTPUT CURRENT AND STABILITY

OPA237 series op amps can drive large capacitive loads.

However, under certain limited output conditions any op

amp may become unstable. Figure 1 shows the region

where the OPA237 has a potential for instability. These

load conditions are rarely encountered, especially for single

supply applications. For example, take the case when a
