3 Description

The TLVx314-Q1 family of single-, dual-, and quadchannel operational amplifiers represents a new generation of low-power, general-purpose operational amplifiers. Rail-to-rail input and output swings (RRIO), low quiescent current (150 μA typically at 5

V) combine with a wide bandwidth of 3 MHz to make this family very attractive for a variety of batterypowered applications that require a good balance between cost and performance. The TLVx314-Q1 family achieves a low-input bias current of 1 pA, making it an excellent choice for high impedance sensors.

The robust design of the TLVx314-Q1 devices provides ease-of-use to the circuit designer: unitygain stability, RRIO, capacitive loads of up to 300-pF, an integrated RF and EMI rejection filter, no phase reversal in overdrive conditions, and high electrostatic discharge (ESD) protection (4-kV HBM). These devices are optimized for low-voltage operation as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V), and are specified over the extended industrial temperature range of –40°C to +125°C.

The TLV314-Q1 (single) is available in both 5-pin SC70 and SOT-23 packages. The TLV2314-Q1 (dual) is offered in 8-pin SOIC and VSSOP packages. The quad-channel TLV4314-Q1 is offered in a 14-pin TSSOP package.
