Rail-to-rail single op amps exhibit a typical input bias current of 2pA
Touchstone Semiconductor  announced that it has added two new, micropower operational amplifiers (op amps) to its “NanoWatt Analog” high-performance analog integrated circuits portfolio: the TS1003  and TS1005 , both available in SC70-5 packaging and ready to ship from Digi-Key , Touchstone Semiconductor’s authorized distributor.
The TS1003 and the TS1005 are priced at $0.35 in 1K-piece quantities. The TS1003 draws 0.6µA and exhibits a 4-kHz gain-bandwidth product (GBWP). The TS1005--the industry’s lowest-power 20kHz gain–bandwidth product op amp--draws 1.3µA. Both the TS1003 and the TS1005 exhibit a typical input bias current of 2pA and rail-to-rail input/output stages.
The TS1003 and the TS1005 op amps are optimized for ultra-long-life battery-powered applications, including micropower active filters, wireless remote sensors, battery and powerline current sensors, portable gas monitors and handheld/portable point-of-sale (POS) terminals.
· Single-Supply Operation: 0.8V to 5.5V
· Low Supply Current: TS1003: 0.6μA (typ); TS1005: 1.3μA (typ)
· Low Input Bias Current: 2pA
· Gain-Bandwidth Product: TS1003: 4kHz; TS1005: 20kHz
· Rail-to-Rail Input and Output Stages
· Value-priced at $0.35 each in 1K-piece quantities
The TS1003 and the TS1005 op amps are fully specified over the -40°C to +85°C temperature range.
