Much of the operation of such devices depends on the ability to cleanly amplify low-power signals from correspondingly smaller sensors. Rohm designed the new TLR377GYZ op amp to fit this requirement. At just 0.88 mm x 0.58 mm x 0.33 mm, it stands out as the smallest available op amp. The wafer-level chip scale package (WLCSP) fits six connections by utilizing a 0.3-mm ball pitch.<\/p>\n<p style=\"text-align: start;\"><strong>The Op Amp&#8217;s Key Specifications<\/strong><\/p>\n<p style=\"text-align: start;\">The <span style=\"color: #ff7a45;\">TLR377GYZ<\/span> (datasheet linked) is a rail-to-rail op amp with a supply voltage range of 1.8 V to 5.5 V. It can operate from a single supply (V<span style=\"font-size: 12px;\"><sub>SS<\/sub><\/span> of 0v to +V<span style=\"font-size: 12px;\"><sub>DD<\/sub><\/span>) or in a dual supply mode (V<span style=\"font-size: 12px;\"><sub>SS<\/sub><\/span> of -V<span style=\"font-size: 12px;\"><sub>DD<\/sub><\/span> to +V<span style=\"font-size: 12px;\"><sub>DD<\/sub><\/span>). It can be used as either an inverting amplifier or a non-inverting amplifier. Low standby current consumption and a shutdown function are some of the operational characteristic optimizations that make the component useful for mobile, wearable, and power-limited applications that require high-accuracy sensing.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"https:\/\/file.flywing-tech.com\/res\/article\/202409100944364436cf93ca1e8395f9dde917d00718e7e1726a9e8.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>Key specifications for the TLR377GYZ<\/em><\/p>\n<p style=\"text-align: start;\"><strong>Big Package Performance in a Small Chip<\/strong><\/p>\n<p style=\"text-align: start;\">Signals from small, low-voltage sensors, such as those for temperature, pressure, and flow, typically operate in voltage and current regimes too small for microcontrollers to process accurately. An op amp increases the sensor\u2019s signal to a usable level. At such low signal levels, amplifiers must not introduce any noise and keep distortion to a minimum.<\/p>\n<p style=\"text-align: start;\">Two of the most common types of signal distortion and errors in an op amp are input offset voltage and noise generation. These two factors are greatly influenced by the size of internal transistors. Larger transistors help to reduce both distortion and error factors. Shrinking the transistor size makes the amp more susceptible to the two problems, which is one of the major challenges in small op-amp designs.<\/p>\n<p style=\"text-align: start;\">Rohm has improved circuit design, fabrication process technology, and component packaging to accommodate smaller parts without increasing amplification errors.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"https:\/\/file.flywing-tech.com\/res\/article\/20240910094511451126dc607e7c380c1206f824ff3d3760cc47167.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>Offset voltage compensation circuit<\/em><\/p>\n<h5 style=\"text-align: center;\"><\/h5>\n<p style=\"text-align: start;\">\n<p style=\"text-align: start;\">Input offset voltage errors are generated, in part, by the difference between Q1 source current (I1) and Q2 source current (I2) due to variations in the two transistors. Rohm developed a proprietary compensation circuit (\u03b1) to adjust for such variations. The circuit allows the part to maintain low input offset voltage errors in the miniature package.<\/p>\n<p style=\"text-align: start;\">Low-frequency noise is another issue with small chip-scale component sizes due to electron scattering. This type of distortion is referred to as \u201cflicker noise.\u201d Rohm addressed flicker noise with process improvements and optimizations in the substrate at the elemental level.<\/p>\n<h5 style=\"text-align: center;\"><\/h5>\n<p style=\"text-align: start;\"><strong>Challenges for Design and Prototyping<\/strong><\/p>\n<p style=\"text-align: start;\">Most PCB layout engineers and technicians are familiar with ball grid array (BGA) packaging with ball pitches down to 0.5 mm. While 0.4 mm pitch is less common, it is no longer considered exotic. However, a 0.3 mm pitch is new enough to disrupt the status quo. The pad footprint construction rules from higher pitch components may not apply. The WLCSP form factor is a silicon flip chip and not light-tight, leaving it susceptible to photoelectric effects. Therefore, designers must take precautions to prevent light exposure while the device is in operation.<\/p>\n<p style=\"text-align: start;\"><img decoding=\"async\" style=\"width: 100%;\" src=\"https:\/\/file.flywing-tech.com\/res\/article\/2024091009453945393064e1e222b08c6fa4687a8fe86d3d6001edc.png\" alt=\"\" data-href=\"\" \/><\/p>\n<p style=\"text-align: center;\"><em>TLR377GYZ-EVK-001 evaluation board.<\/em><\/p>\n<h5 style=\"text-align: center;\"><\/h5>\n<p style=\"text-align: start;\">\n<p style=\"text-align: start;\">To help with prototype and test applications, Rohm developed a carrier evaluation board in the size of an SSOP6 IC. The board mounts with castellated holes (essentially a via cut in half) with a pin pitch of 1.27 mm. Rohm suggests that the evaluation board be used for either component evaluation or as a replacement on a PC board with an existing spot for an SSOP6 packaged op amp.
