Single op-amp with rail-to-rail input and output and an 8 MHz gain-bandwidth, in a SOT-23-5. It runs from a single 2.5 to 5.5 V supply at about 1.1 mA, swings within millivolts of both rails, and holds a 1 mV input offset, which suits it to sensor buffering and active filters on a 3.3 or 5 V board. A 4.5 V/us slew rate handles moderate signal speeds. The single of the TSV91x family (dual -2, quad -4).

Pinout

Pin	Name	Type	Function
1	OUT	output	Op-amp output. Rail-to-rail; high output current 35 mA typ (Isink 32 mA typ / Isource 35 mA typ at Vcc = 2.5 V). Low VOH/VOL: within 15 mV of the rail at RL = 10 kΩ.
2	VCC-	power_in	Negative supply / ground. Total supply voltage (VCC+ − VCC−) from 2.5 V to 5.5 V (2.3 V to 5.5 V at Top ≥ 0 °C). Absolute maximum 6 V.
3	IN+	input	Non-inverting input. Rail-to-rail input; common-mode range (VCC−) − 0.1 V to (VCC+) + 0.1 V. Input bias current 1 pA typ (10 pA max at 25 °C).
4	IN-	input	Inverting input. Rail-to-rail input; common-mode range (VCC−) − 0.1 V to (VCC+) + 0.1 V. Input offset voltage 1.5 mV max (A grade) / 4.5 mV max (standard), 5 µV/°C drift typ.
5	VCC+	power_in	Positive supply. 2.5 V to 5.5 V operating (2.3 V to 5.5 V at Top ≥ 0 °C). Supply current per channel 820 µA typ, 1.1 mA max. Absolute maximum 6 V.
