General-purpose single op-amp with rail-to-rail input and output on a single 1.8 to 5.5 V supply, in a tiny SC70-5. It offers 1 MHz of bandwidth and EMI-hardened inputs at low cost and low quiescent current, which suits it to buffering, filtering, and level-shifting on space- and power-limited boards. It drives light loads close to both rails. A cheap, small workhorse single for 3.3 and 5 V systems, the single of the TLV900x family.

Pinout

Pin	Name	Type	Function
1	OUT	output	Amplifier output. Rail-to-rail output stage; drives capacitive loads up to 500 pF and swings to within millivolts of V+ and V-.
2	V-	power_in	Negative (low) supply or ground for single-supply operation. Total supply (V+) - (V-) rated 1.8 V to 5.5 V (7 V absolute maximum).
3	IN+	input	Noninverting input. Rail-to-rail input common-mode range (V-) to (V+); low input bias current of 5 pA typical.
4	IN-	input	Inverting input. Rail-to-rail input common-mode range (V-) to (V+); low input bias current of 5 pA typical.
5	V+	power_in	Positive (high) supply. Total supply (V+) - (V-) operates 1.8 V to 5.5 V (7 V absolute maximum). Bypass to V- with a low-ESR capacitor near the pin.
