PDIP (N)-14-181.42 mm² 19.3 x 9.4

The TLV2322 and TLV2324 (TLV232x) operational amplifiers are in a family of devices that have been specifically designed for use in low-voltage, single-supply applications. This amplifier is especially useful for ultra-low-power systems that require devices to consume the absolute minimum of supply currents. Each amplifier is fully functional down to a minimum supply voltage of 2.7V, and is fully characterized, tested, and specified at both 3V and 5V power supplies. The common-mode input voltage range includes the negative rail and extends to within 1V of the positive rail.

These amplifiers are specifically targeted for use in very low-power, portable, battery-driven applications with the maximum supply current per operational amplifier specified at only 27µA over the full temperature range of –40°C to +85°C.

Low-voltage and low-power operation is possible by using the Texas Instruments silicon-gate LinCMOS™ technology. The LinCMOS technology process also features extremely high input impedance and ultra-low bias currents making these amplifiers an excellent choice for interfacing to high-impedance sources such as sensor circuits or filter applications.

To facilitate the design of small portable equipment, the TLV232x is made available in a wide range of package options, including the small-outline and thin-shrink small-outline packages (TSSOP). The TSSOP package has significantly reduced dimensions compared to a standard, surface-mount package. The maximum height of only 1.1mm makes this device particularly attractive when space is critical.

The device inputs and outputs are designed to withstand –100mA currents without sustaining latch-up. The TLV232x incorporates internal ESD-protection circuits that prevent functional failures at voltages up to 2000V as tested under MIL-STD 883C, Method 3015.2. However, exercise care in handling these devices because exposure to ESD potentially results in the degradation of device parametric performance.
