New micropower op-amps Zero trade-offs TSV6x family delivers the best power-to-speed ratio March 2010 www.st.com/stdlinear Enlarged TSV6x family for extended battery life and high accuracy at low voltage STMicroelectronics has recently introduced three new micropower op-amp families for power saving in low-voltage applications. The TSV619x, TSV629x and TSV639x, based on previous TSV6x families, further reduce power consumption for handheld, battery-supplied applications. They offer an outstanding merit factor. For the same consumption as the TSV6x, they offer a gain-bandwidth product increased by a factor of 3 and have twice the slew rate value. They are intended for non-inverting (G ≥ +4) or inverting (G ≤ -3) gain configurations for stability reasons. They keep the same advantages as the TSV6x families: precision, low supply voltage, low input currents, as well as tiny packages. Key features and benefits Features Benefits Ultra low supply voltage: 5.5 V down to 1.5 V Ideal for battery-powered devices, extends battery life Large offer - 6 ranges of power/speed: From 10 µA/450 kHz up to 60 µA/2.4 MHz High merit factor extends battery-life Standby current: 5 nA typ Significantly reduces consumption when not in use, thus extends battery life Very low input offset voltage: Down to 500 µV max Good precision for small signal conditioning Low input bias current: 1 pA typ Ideal for high impedance sensors Tiny packages: SC70-5/6, SOT23-5/6/8, MSO8/10 Board space saving High ESD tolerance (≥4 kV HBM) High EMI rejection ratio Design robustness, high reliability TSV6xx and TSV6x9x: two complementary families to better fit application needs 33 27 -100 0 -140 TSV63x -180 Vcc = 5 V, Vicm = 2.5 V Vload = 2.5 V, RL = 10 kΩ, CL = 100 pF -20 10 4 10 5 gain phase Supply current (µA) 20 23 Phase (°) Gain (dB) TSV639x T = 25 °C T = 125 °C 20 T = -40 °C 17 13 10 7 10 6 Frequency (Hz) 3 -220 0 0 10 7 Vicm = Vcc/2 1 2 3 Supply voltage (V) Typical applications QQ QQ QQ 2 Battery-powered devices Signal conditioning, filtering Medical handheld devices QQ QQ QQ Smoke detectors Low-side current sensing Photodiode pre-amplification Number of operators Input offset voltage Input bias current Supply current per operator GBP typ.
