TLV904x Micro-power, 1.2-V, RRIO, 350-kHz Operational Amplifier for
Cost-Sensitive Applications
TLV904x achieves excellent balance between
1 Features
performance and power consumption. The device
delivers optimum gain bandwidth, low noise, and high
cap load drive while consuming just 10 µA of
quiescent current. This enables customers to achieve
their desired performance targets and helps them
save valuable battery power. Further power savings
can be achieved from low-voltage operation at 1.2 V
compared to a 1.8-V, 3.3-V, or 5-V operation.

Operational from supply voltage as low as 1.2 V
Rail-to-rail input and output
Low quiescent current: 10 µA/ch
High gain bandwidth product: 350 kHz
Low integrated noise of 6.5 µVp-p in 0.1 Hz –10 Hz
Low input offset voltage: ±0.6 mV
Low input bias current: 1 pA
The robust design of the TLV904x family simplifies
circuit design. These op amps feature rail-to-rail input
and output, unity-gain stability, an integrated RFI and
EMI rejection filter, and has no-phase reversal in
overdrive conditions.
Unity-gain stable
Robustly drives 100 pF of load capacitance
Internal RFI and EMI filtered input pins
Wide specified temperature range: –40°C to 125°C
Low power CMOS amplifier for cost-optimized
applications
The TLV904x devices include a shutdown mode
(TLV9041S, TLV9042S, and TLV9044S) that allow the
amplifiers to switch off and enter into a standby mode
with typical current consumption of less than 150 nA.

3 Description
The low-power TLV904x family includes single
(TLV9041), dual (TLV9042), and quad-channel
(TLV9044) ultra low-voltage (1.2 V to 5.5 V)
operational amplifiers (op amps) with rail-to-rail input
and output swing capabilities. These op amps provide
a cost-effective solution for power and space-
constrained applications such as battery powered IoT
devices, wearable electronics, and personal
electronics where low-voltage operation is usually
desired. TLV904x is one of the few op amp families in
the industry that enables 1.5-V coin cell battery
powered applications.
